Candidate interview experiences
First-hand accounts from people who interviewed at Bluecrew.
Software Engineer
The interview process involved one quick initial round, followed by three consecutive rounds held a week later. The interviews focused on LeetCode problems and system design. The questions were designed to progressively reveal more complexity as the candidate worked through them.
- Can you redesign Google Calendar using object-oriented programming principles?
Software Engineer
For the interview, they started with a college-level question about programming a bingo game, which seemed odd. They had me write the code on a shared screen. I had to ask if they were actually developing bingo apps because the question felt too basic for a senior role.
- Make a bingo game, lol. Code a 5x5 array.
- What's the O notation runtime for your bingo game solution?
- Can you explain your thoughts on our big data challenges?
Principal Software Engineer
It started with a recruiter chat, pretty chill. Then I had a pretty intense hour-long call with the Director of Engineering, they really dug into use cases. After that, there was a software system design round.
- Can you design a system that includes about 4-5 RESTful API endpoints, persistence, in-memory caching, and authentication via username/password with session management using authorization tokens?
- Also, write tests for the code you design.
- Finally, deploy the system so it has a publicly accessible URL.
