There was an Online Assessment (2 questions - 1 easy and 1 medium), followed by a Phone Screen (2 questions of increasing difficulty). The interviewer asked for a more optimal approach after I provided a solution.

The first stage was an invitation to an online coding skill test. You could choose the programming language. The tasks were mostly about writing algorithms and were completed with limited time.

The OA was sent to me after 1 month. I received a notice that there would be an interview in 2 weeks. I waited 2 months until the interview took place.
