Application

I applied online. The process took 2 weeks. I interviewed at Everon (Amsterdam (Netherlands)) in June 2020.

Interview

After a few days of submitting my application, a recruiter sent me an email with a PDF file attached describing the challenge that I need to solve. Basically it is an API for charging stations which you need to implement by following certain requirements:

- All endpoints need to run in O(log N) except retrieving the list of all charging sessions.
- The implementation must be thread-safe

You submit your assignment by sending the project zipped file directly by email which is unprofessional imo. In my case they rejected my submission the same day, however when I asked for feedback, they didn't reply. How unfortunate is that considering people invest their time and energy into a project then they get a yes/no response.

Interview Questions

  • Implement an endpoint that returns the number of started and stopped charging sessions for the past 1 minute. The implementation has to run in O(log n)   1 Answer
