Master The Behavioral Interview [Part 22] - Do Mock Interviews

Software engineers love working and studying solo, but this is extremely difficult with behavioral interviews. This lesson teaches you:

- Why behavioral interviews are inherently collaborative and effectively require mock interviews to master
- How to get the most value from your mock behavioral interview sessions

Ace The ML System Design Interview [Part 3] - Big Picture Design

A strong big-picture system design is crucial for success in machine learning system design interviews. It's not about drawing a perfect diagram immediately, but about demonstrating an understanding of the system's components and their interactions. Here are the core points from this lesson:

- Identify the inputs and outputs of the system during the alignment phase to establish a foundation for building the diagram
- Start with the user and the service, then progressively add components, especially those involving machine learning, to illustrate the flow of data and processes
- Break down machine learning components beyond a single "ML system" box to show the different stages and types of models involved
- Include essential infrastructure elements, such as feature stores, to demonstrate a comprehensive understanding of the system
- Iterate on the diagram, adding or modifying components as a deeper understanding of the problem and its requirements develops

The Most Important Thing To Do After You Get Laid Off

As a software engineer, you naturally have a lot of leverage as a highly sought after, highly-skilled worker. If you end up getting laid off, take the opportunity to use that leverage and seriously think about bettering your future.

Here are the core points:
- **Take the time to introspect about career direction** - When you're working, it's way too easy to get lost in the hustle and just trudge from project to project. After you're laid off, you now have the mental freedom to really think about where you want to go with your career. This will take at least several days, maybe even weeks. Try to envision what the perfect job looks like to you and make that your goal. Ask yourself where you want to be 5 or 10 years from now.
- **Think about what makes you happy** - This sounds cliched, but it's 100% true. There's no point min-maxing your compensation and level if you're fundamentally unhappy while doing it. The tech industry is such a broad space: There is a right opportunity for everybody where they can grow their career and be happy while doing it. But in order to get that opportunity, you need to discover what genuine passions you have.

Master The Behavioral Interview [Part 11] - Interviews Are A 2-Way Street

One of the easiest ways to tank your career as a software engineer is to join the wrong company or team. Despite this, so many software engineers squander their time in behavioral interviews to uncover extremely valuable information about the quality of an organization. This lesson teaches you:

- Why not having thoughtful prepared questions to ask the interviewer makes you look really bad in a behavioral round
- The critical career importance of behavioral interviews being a 2-way street

DSA Crash Course [Part 26] - Sum List Approach

In this lesson, Alvin explores the strategy to solving the following interview problem:

> Write a function, *sum_list*, that takes in the head of a linked list containing numbers as an argument. The function should return the total sum of all values in the linked list.

```
a = Node(2)
b = Node(8)
c = Node(3)
d = Node(-1)
e = Node(7)
a.next = b
b.next = c
c.next = d
d.next = e

# 2 -> 8 -> 3 -> -1 -> 7
sum_list(a) # 19
```

```
x = Node(38)
y = Node(4)
x.next = y

# 38 -> 4
sum_list(x) # 42
```

```
z = Node(100)

# 100
sum_list(z) # 100
```

Grow From Mid-Level To Senior Engineer [Part 8] - Fill In The Gaps

Senior engineers solve fundamentally different problems compared to mid-level engineers. This lesson teaches you:

- The expectation for senior engineer mindset and behavior when problems arise in a project they're working on
- The types of problems that mid-level engineers tend to avoid
- The types of problems that senior engineers uniquely solve compared to more junior engineers

Don't Waste Your 1 on 1s. Build The Relationship

Why should you build the relationship in 1 on 1 meetings?

True or false: Small talk is okay in 1 on 1 meetings to break the ice and learn more about the other person's life outside of work.

Why are deep relationships needed in tech, especially at senior levels?

One-on-one meetings are a foundational tool for building trust and social capital within a company. Especially in medium to large organizations, relationships drive execution—and one-on-ones provide a structured, intentional space to cultivate those relationships.

- **Build social capital early**: Scheduling one-on-ones with key teammates—engineers, designers, PMs, and adjacent team managers—early on helps lay the groundwork for future collaboration. This “trust bank” can be drawn on when challenges inevitably arise.
- **Treat relationships as human endeavors**: There's no formula for connection. These conversations are opportunities to build real understanding, not just to exchange project updates.
- **Welcome small talk, especially at first**: In early one-on-ones, light conversation about emotions, hobbies, and general well-being helps establish rapport. This human connection builds the trust needed for deeper collaboration later.
- **Shift toward deeper conversations over time**: Once a working relationship is more established, focus should evolve toward more meaningful topics—emotions, motivations, and work challenges—while still leaving space for the personal.
- **Listen with genuine care**: The most effective relationships are built on authentic interest. It’s not enough to ask personal questions—true connection comes from caring about and following up on what others share.

By using one-on-ones intentionally and empathetically, it's possible to create strong, lasting connections that enhance both individual performance and team effectiveness.

20 Years Of Fighting Procrastination [Part 8] - Do Work When You're Working

When engineers say they’ve been “working all day,” that time often includes distractions, shallow tasks, or unnecessary overhead. To truly be productive, you have to focus on high-leverage, distraction-free work. Here are the core points from the lesson:

- Real productivity comes from deep work—uninterrupted, focused effort on cognitively demanding tasks—not from staying busy or checking email 50+ times a day
- Recognize and minimize "startup costs" like syncing code, building the app, and reviewing changes, so you can spend more time in the value-generating loop of building and debugging
- Block off long stretches of time for deep work rather than relying on scattered 30–45 minute sessions that get consumed by overhead
- Automate or script repetitive setup tasks (e.g. syncing and builds) to reduce friction and start meaningful work faster each day
- Prioritize difficult, ambiguous tasks early—they often influence downstream work, and avoiding them leads to fake progress and missed deadlines

How The Top 1% Of Engineers Are Judged

As a former VP of Engineering at Amazon, Ethan has the unique ability to share how the senior-most engineers were evaluated within Big Tech. These are the top few percent of engineers in the company (Staff Engineers, Principal Engineers, Distinguished Engineers, etc), and the expectations are incredibly high.

**Key insights:**

- **At very senior levels, technical excellence is table stakes.** The top-performing engineers use their technical expertise to help the business. 
- **The dynamic with company leadership is important**: these engineers must be proactive in helping the business, and not simply the "guru on the hill" who provides answers when asked.
- **There are different modalities to get to a very senior level**, e.g. CTO model, technical expert, product engineer, and others. It's ok if you don't want daily meetings with company leadership, but you must be working on a valuable enough problem that can merit an engineer of that seniority.
- **Finding a good manager is critical for both ICs and managers**. Two ways to evaluate this are (1) find a leader who has grown many people and (2) find a leader who is advancing rapidly in their career.

[**Ethan Evans**](https://www.linkedin.com/in/ethanevansvp/) is a retired Amazon VP who now teaches managers how to break into executive levels. He was at Amazon for 15 years, and he became a VP in 2013 until he left in 2020. Ethan shares valuable insights for anyone interested in management or career development.

DSA Crash Course [Part 39] - Depth First Values Approach

In this lesson, Alvin explores the strategy to solving the following interview problem:

> Write a function, *depth_first_values*, that takes in the root of a binary tree. The function should return a list containing all values of the tree in depth-first order.

```
a = Node('a')
b = Node('b')
c = Node('c')
d = Node('d')
e = Node('e')
f = Node('f')
a.left = b
a.right = c
b.left = d
b.right = e
c.right = f
#      a
#    /   \
#   b     c
#  / \     \
# d   e     f

depth_first_values(a)
#   -> ['a', 'b', 'd', 'e', 'c', 'f']
```

```
a = Node('a')
b = Node('b')
c = Node('c')
d = Node('d')
e = Node('e')
f = Node('f')
g = Node('g')
a.left = b
a.right = c
b.left = d
b.right = e
c.right = f
e.left = g
#      a
#    /   \
#   b     c
#  / \     \
# d   e     f
#    /
#   g

depth_first_values(a)
#   -> ['a', 'b', 'd', 'e', 'g', 'c', 'f']
```

```
a = Node('a')
#     a

depth_first_values(a)
#   -> ['a']
```
