The process was quite lengthy, but this was likely because I was interviewed during Christmas/New Year's.

Great thanks to my recruiter; he was a very helpful and responsive guy.

Overall, there were 5 rounds, as you can find on their website. However, this really depends on the team and location.

R1: Recruiter call. General get-to-know questions and some light technical topics. Duration: 30 minutes.

R2: Hiring Manager/Team Lead call. More get-to-know questions, some behavioral questions, and more light technical/workflow-related questions.

R3: This comprised of two parts: a Codility online assessment and a take-home assignment. For Codility, there were two questions in 70 minutes in my case. The difficulty was about LeetCode Medium or Codeforces 800. Be aware that the platform may not have your preferred language or an up-to-date version of it. The assignment was usually to design a prototype component, which included testing and some benchmarks for my case.

R4: The "final interview." I met with three engineers, and we went through a whole array of questions. Some were behavioral (STAR format), some were job-related technical questions, and also a review of your homework from the previous round. It really threw me off during this round, as I was expecting a FAANG-like interview format. Surprisingly, there was no coding interview, and the "high-level design" we did was more of a discussion rather than an interview. There were some technology-specific questions that I stumbled on, but overall, it went okay.

R5: Right after R4, I hopped on a call with my recruiter, and we tried to get the references finalized as quickly as possible because it was very near Christmas at that time. You will have references from two of your previous managers and two of your peers. They will contact them until they get at least two responses from the list you provided.

A couple of weeks later (this was mainly due to the Christmas/New Year's breaks + COVID stuff), I got on a call with the hiring manager, and we talked about my interview experience. After that, on the same day, the recruiter told me I got accepted.

There were no negotiation rooms for the salary, but the stock was huge, which gave the total compensation a significant bump compared to an average company in the region.

What's the difference between different kinds of testing methodologies?

For example, unit tests and acceptance tests.
