I applied online then I received a phone call from HR, it was simple HR screening, then I was asked to perform a personal aptitude test. The second round was a skype video call with a hiring manager and a project manager, it was a positive experience as both of them were knowledgeable and pleasant, and it was about my previous experience and they presented what the role could be. I was then called for a technical assessment on a skype video call with one of the co-founders, it was about solving complex puzzles and optimization.
