Stop Getting Ghosted With Your Reachouts - How To Write A Great Cold Message

If you're a software engineer, you are likely going to do a cold reach out at some point in your career. This is almost always true when you're a junior engineer and don't have too deep a network yet. However, most software engineers go about this aspect of professional networking in the wrong way, especially when it comes to job searching and interviewing.

Here's how to write a cold message that actually has a chance of getting a response:

- **Mention your own background** - If you have any credibility, use it. What accomplishments do you have? What makes you special compared to everyone else and deserving of a response from this person?
- **Have a specific request** - The more pinpointed your ask is, the less effort it takes for the other person to figure out how to help you. Don't just ask for help with things like "career guidance" or "helping you find a job" - These categories are far too broad. Ask for tips on clearer areas like how to resolve disagreements in cross-team meetings or how you can pass behavioral interviews with &lt;50 person startups. For more advice here, check this out: [Asking Effective Questions That Get Great Answers Quickly](https://www.jointaro.com/lesson/HV8sq75WxM9VhK0dhUun/asking-effective-questions-that-get-great-answers-quickly/)
- **Find commonality** - Having common ground is one of the most important factors with a successful relationship. Whether it's working on the same tech stack, coming from the same school, or playing the same video game, share that commonality to make yourself feel more familiar.
- **Build them up** - At the end of the day, everyone enjoys being praised. Put them on a pedestal and explain why *their* input in particular is valuable to you. Show that you didn't send the exact same message to 100+ different people.
- **Make up follow-up items clear** - Don't just ask for "guidance" or "mentorship": Make it clear what's the exact form of help you want? Is it a link to a useful blog post or video? Is it a 30 minute 1-on-1 meeting?

How The Best Software Engineers Learn A Tech Stack - The Lego Model

- "The Lego Model" is a way to view the world and understand your learning journey as a software engineer.
  - Technical components (e.g. rendering a list of items) are the individual legos
  - Complete products (e.g. a food delivery app) are the full lego creations
- There are 3 axes to evaluate your legos:
  - **Quantity:** How many you have
  - **Quality:** How good and sturdy your legos are
  - **Commonality:** How "in demand" your legos are (i.e. how many creations they can fit into)
- Most earlier-in-career engineers understand the 1st axis of quantity and incorrectly spend a lot of time learning different tech stacks and frameworks.
- Those same engineers often don't even realize the 2nd and 3rd axes exist:
  - When they learn a component, they will build it out with very low quality.
  - They will learn "flashier" components that aren't even used by most products/companies.

For examples on how to excel at the 2nd and 3rd axes, check out the related resources below!

How To Effectively Leverage Skip Level 1:1s

In this lesson, we discuss that the "skip" is the person that your manager reports to - It's what happens when you "skip" your manager when going up your reporting chain. 1 on 1 meetings with your skip are tricky as you can't talk to them the same way you would to your direct manager:

Here's how you can get maximum value from your skip 1 on 1s:

- **Understand your organization's overall strategy** - Since your skip is operating at a higher-altitude, they will be naturally well equipped to answer this question. Ask them what their priorities are, and you can then weave them into your own work to increase your impact.
- **Share "on the ground" insights** - Skips are generally pretty disconnected from nuts and bolts day-to-day work due to their seniority. As an IC, you are well-equipped to share what that experience is like as that's your life. This is really valuable, if you can come up with insights on how to improve this experience.
- **Be honest with feedback** - There's not much value sucking up to your skip and telling them that they're great and everything is going great because of that. Be candid and unafraid to share real problems with how the organization functions.

[Masterclass] How To Build And Grow Tech Products To 500k+ Users For Free

Here are our Top 5 points from this session:
- **Side projects are incredibly powerful** - They improve your portfolio, increase your coding velocity, and give you holistic experience around building products end-to-end.
- **Care deeply about quality** - Users notice when your app or website is buggy. Strive to cover all edge cases and provide a truly polished experience.
- **Eat your own dogfood** - The best way to know how to improve your product is to use it yourself. This was a staple of Meta's engineering culture.
- **Least clicks design** - At the end of the day, it doesn't matter how "pretty" your product looks if it isn't efficient. Think about how you can have your "hero flow" take as few clicks as possible.
- **Understand SEO** - Work backwards from what people will be searching for when they need a product like yours. Then have those words in your product title and relevant metadata.

Level Up Your Code Quality As A Software Engineer [Part 13] - Lay Out The Plan

It's tempting as a software engineer to leap straight into the code and start being productive. However, this can often cost you time in the long-term, especially with more technically complex tasks. This lesson will teach you:

- Why it's important to create a plan to increase your code quality, move faster, and build up relationships with your teammates
- What goes into a rock-solid coding plan (hopefully you were paying attention during the prior parts of the course!)
- Exactly what a good technical plan looks like with a concrete, real-life example from Taro

[Case Study] Solving A Multi-Million $$ Instagram Bug

- A big part of moving from L4 (mid-level) to L5 (senior level) is being able to create your own scope. You can't just expect a perfect suite of projects to come from your manager.
- Like in this session's case study, bugs are a great source of finding your own scope!
- The bug was very slight: Instagram story ads started off on the wrong part when they were resurfaced to a user. As an Android engineer, Alex discovered this in IG Android initially. This bug had been in production *for over a year* at this point.
- How Alex expanded the scope after finding this bug:
  - Worked with iOS to see if the bug was there (it was)
  - Worked with PMMs to confirm that this violated the advertiser contract and merited a refund. This made the bug an immediate SEV.
  - Worked with a data scientist to figure out exactly how many times this bug occurred and calculate the exactly refund to advertisers ($2M+)
  - Put the fix behind an A/B test to measure impact and make sure it was working
- How you can incorporate the learnings from this case study:
  - Be detail-oriented. At Big Tech in particular, seemingly small issues can have massive impact.
  - Don't just silently fix bugs. Take the time to figure out its entire scope - It could be a SEV!
  - Understand the world outside of yours. Look for opportunities to bring in others (especially those of different roles) into what you're working on to expand scope for everyone!

Level Up Your Code Quality As A Software Engineer [Part 16] - One Diff, One Thesis

One of the biggest and easiest ways to level up your code doesn't even lie in the code itself and is about how you split it up when submitting it for code review instead. This lesson will teach you:

- The most common way low-performing software engineers mess up their code when submitting it for review
- Why championing the concept of "One Diff, One Thesis" massively boosts your productivity alongside your code quality
- How to tell whether your pull request follows the principal of "One Diff, One Thesis" or should be broken up into smaller pull requests instead
- How to split up your technical task or project into chunks, so you can map out its pieces to a series of pull requests following "One Diff, One Thesis". We do this with an in-depth example further digging into the login flow

Write A Stellar Resume As A Software Engineer [Part 4] - 1 Resume To Rule Them All

Writing tons of different resumes is one of the easiest ways to waste time and overwhelm yourself on the software engineer job search. This lesson teaches you:

- Why you should only have 1 resume, especially if you're an earlier-in-career engineer
- Why "full-stack" engineer is often a trap for more junior engineers
- How to figure out the 1 resume you should write
- What to do if you really can't write just 1 resume (i.e. how to break the tie)

Grow From Mid-Level To Senior Engineer [Part 3] - At A Glance: Mid-Level Vs. Senior

What exactly does it mean to be a mid-level engineer vs. a senior engineer? What's the gap? This lesson teaches you:

- What it means at a high-level to be a mid-level engineer vs. a senior engineer
- The types of projects mid-level engineers work on vs. a senior engineer
- The ownership and scope difference between a mid-level engineer vs. a senior engineer
- The difference in organizational complexity between mid-level engineers and senior engineers

20 Years Of Fighting Procrastination [Part 3] - Build A System

Most people rely on fluctuating willpower to be productive—but the most effective creators use systems. Here are the core points from the lesson:

- Systems make good behavior automatic by reducing cognitive load and accounting for natural fluctuations in willpower, energy, and focus
- Structure your day around your strengths—use mornings for disciplined deep work, afternoons for accountability-based tasks, and evenings for creative exploration
- Focus on generating artifacts like notes, calendar blocks, or test plans to capture progress, clarify your thinking, and preserve valuable context
- Habit stacking and predefined triggers make consistent output easier and help you avoid relying on short-term motivation or memory

Amazon Case Study: The Ultimate Guide To Navigating A PIP

Case studies are valuable to (1) realize that you are not alone and (2) learn from the experiences of others and see what you can apply.

We’ll start with a new grad Amazon engineer who joined during the pandemic.

- **Before**: First job out of college, was on Focus after 6 months
- **During**: Shocked when they found out (URA quota suspected). Manager became more “HR-like”, less candid
- **After**: Went through the PIP and failed, even though they showed improvement

You did everything right. That wasn’t the problem.

Some people move up because they ask for more.\
Others move up because they already act like they own more.\
Then there’s the third kind—the ones still waiting for someone to notice.

If that feels familiar, this section will explain why hard work alone isn’t the lever you think it is.

What Is An Engineering Manager?

In this lesson, we explore what an Engineering Manager (EM) is, what they do, and how understanding their incentives helps us collaborate more effectively.

- We learn that an EM is a leadership role supporting engineers, typically managing 8–12 reports, though team sizes can vary widely.
- We understand that the EM’s primary goal is ensuring the team consistently delivers meaningful impact.
- We recognize that knowing an EM’s core incentives helps us work with them more effectively and collaborate better overall.
- We review the two major career tracks in tech: the IC (individual contributor) track and the M (management) track, which begins with the EM role.
- We note that the EM is the first layer of management, with roles like Director, VP, and CTO above them, and that most of us will report to an EM unless we reach very senior IC levels (e.g., L8/L9).

[Masterclass] How To Write A Stellar Tech Resume That Gets You More Job Opportunities

Writing an effective resume is crucial for succeeding within the tech industry, especially for software engineers. It's the primary step you need to clear before getting a chance with an interview opportunity. Unfortunately, there is a lot of misinformation around how to write a good resume: For 80%+ of junior software engineers struggling to break into tech, a poorly written resume is one of the main causes.

All that being said, here are our Top 5 points from the sessions (in no particular order):
1. *Remember that a recruiter is reading your resume and will, on average, only spend ~10 seconds on it*
    - They are almost certainly non-technical. Make things very accessible and easy to understand: Avoid jargon!
    - Be ruthlessly concise. For the vast majority of cases, your resume should only be 1 page.
2. Having a spelling or grammar mistake is the easiest way to get your resume thrown out
    - You have an effectively infinite amount of time to polish your resume. If you can't even catch basic mistakes like these, it shows that you have poor attention to detail or bad prioritization.
3. Show, don't tell
    - Don't just say that you're great, prove it
    - Example: Talking about the Android apps you've built with 100k+ users is much more effective than just saying you're a great Android engineer
4. Traps to avoid:
    - Having a summary section at the top
    - Self-rating yourself across skills
5. In the end, your resume needs to be approved by a human, not just an ATS
    - Making your resume very weird to "optimize" for the ATS is the epitome of winning a battle to lose the war. It's pointless

Nail Your Promotion As A Software Engineer [Part 4] - Do It For The Right Reasons

It's easy to become promotion-obsessed, especially at top companies like FAANG where promotions are so meaningful. However, this is a toxic mentality to have that ultimately hurts your career ambitions. This lesson teaches you:

- How to strike a delicate balance between deliberately pushing for promotion and having a healthy growth mentality
- The optimal mindset to have to get to extremely senior engineering levels
- Common pitfalls promotion-obsessed engineers fall into and what you should do instead for each of those situations

Level Up Your Code Quality As A Software Engineer [Part 11] - Case Study: Signup Form Edge Cases

So how exactly do you figure out the edge cases with a piece of software? Well, it's hard work, especially as the volume of edge cases scales up exponentially with the complexity of the underlying feature. This video will teach you:

- A process to think through edge cases step-by-step through the stack with an *incredibly* in-depth example covering one of the most classic features virtual every tech company ever has: The email and password signup flow
- Why Big Tech companies hire so many software engineers to build out seemingly basic CRUD applications (hint: They're not basic, not at all, and the signup form case study will prove that to you)

Create An Onboarding Doc

The **onboarding doc** is a reference guide as you join the company. This document is literally designed for you, outlining your role + team, people to meet, and how you can get started. Generally, your manager will provide an onboarding doc for you, but you should feel free to augment or create your own if the doc is lacking. This is a great place to collaborate and deepen your relationship with your manager -- point out further areas of discussion.

Components of a good onboarding doc:

1. Team charter (translated down from the company mission)

2. Partner teams + people

3. Expectations + milestones 

   1. These should be clearly defined so it'll be clear if you achieved the expectation or not

4. Project ideas with t-shirt sizing

5. Engineering rubric or career matrix for your role, if one exists
