Positive ExperienceNo Offer

Process

  1. Initial discussion with 2 engineering teammates. Mostly only motivation and culture fit.
  2. Home take code testing.
  3. Review and discussion on the code testing submission.
  4. Interview feedback by HR.
  5. Two rounds of culture fit interviews (which they called board interview/formula interview).

Questions

The main technical interview is in step 3. A lot of why, what if, and how questions were asked.

For example, the code testing consisted of:

  • 1 SQL task
  • 1 algorithm related to in-memory cache and searching
  • 1 skeleton project

For task 2:

  • Why did you design/choose the solution (my case is Map)?
  • What is the time and space complexity of the algorithm?
  • Are there any more solutions you can think of?
  • What is the benefit of [a certain kind of technique] (my case is in-memory cache)?

For task 1:

  • If the requirement changed to [new requirement], how will you handle the case? (My case is when joining 2 tables, how to find records that are not matched).
  • How to improve SQL performance? What can cause a slow query? Notice they will ask if there are any cases of slow update/delete.
  • Is creating more indexes better?

For task 3:

  • Again, why did you design/choose the solution (my case is AtomicLong)?
  • Also, I was asked to find bugs in the code submission.
  • Also, questions about concurrent calls.

So, it looks like performance is one of their major concerns.
