Had a phone interview with one of their devs. 45 mins long. Had three questions. They gave me an API and I had to use it to solve some basic questions. Would be a good question to revise Hashing, Data Structures. Wasn't too specific on complexity.

Entretien
I applied online and received an email a few weeks later from a recruiter for a technical phone interview, which lasted for an hour.
I got a response within days, they invited me to an onsite interview where they did two interviews ~45 each, coding on a provided laptop. I stumbled for a bit trying to find an efficient solution. The interviewers were friendly, guiding me with possible improvements and pointing out edge cases. I got the email a week later saying they would be looking for other candidates.
