Contacted by a recruiter through a resume database.

Completed a HackerRank coding challenge, a 30-minute phone screen with the recruiter, and then two one-hour technical phone interviews.

The interview questions were pretty standard (algorithms/data structures).

Would have rated the experience as positive, except my recruiter was pretty unresponsive throughout the process (for example, they would ask for my availabilities and then not reply for a week, or schedule my interview for a time I had indicated I was not available).
