Senior Software Engineer Interview Experience
Process
Online technical screen: four questions in 70 minutes on a HackerRank-like platform. Each question is a little harder than the last. Definitely get something working for each question, even if you don't pass all unit tests. I was able to pass the assessment with failing tests on the last two questions.
Power Day (as they call it) consisted of 4 interviews:
- 1 system design
- 1 coding
- 1 case interview
- 1 behavioral
This was pretty standard, except for the case interview, which I found to be easy. Just keep talking; come up with ideas and justifications for the problem they present.
Questions
Design a credit card account management system.
