1. Recruiter texted in LinkedIn IMs.
2. Gave me two medium graph problems for home with a one-hour limit.
3. Three 45-minute back-to-back interviews: a) OOP design coding b) DSA - easy-medium tree problem c) System design interview (The interviewer didn't come due to tech problems - rescheduling took one month).
4. Culture fit interview.
5. Two team fit interviews.
6. Offer.
7. Negotiations.

Process took five months! I blame the recruiting team for being so slow, even though for a fact I know they had available managers.

DSA Home Assignment:

A kind of "Number of Islands" problem on Leetcode.

Given a tree of skills (like in an RPG game) in the form of an array, and a skill number, return the number of skills that are needed to learn before the target skill number.

OOP Design:

Design a vending machine.

DSA Livecoding:

Design a tree and assign to each node, that doesn't have a sibling, a sibling (as an additional field in the node). Bonus question was to make it thread-safe.

System Design:

1. Difference between microservices and monolith systems
2. Types of APIs
3. What is REST
4. What is a Proxy API
5. What does Kubernetes include in its system
6. What is an orchestrator
7. How to track so many services in a microservices architecture
8. What is CDN
9. What system would you use for a marketplace?

Culture Fit Interview:

1. Tell me about a time you had an argument with your teammate.
2. Tell me about a time when you failed.
