Very negative and disrespectful experience. I applied through their website and scheduled a call with the product strategist. He had some general questions but when we went to the "problem solving" questions that's where things got weird. He first asked me to calculate when they would break even based on some variables. He replied to my answer "OK. Let me ask you something easier." and then asked the sum of all numbers between 0 & 100. I am not sure if it was his purpose to throw me off my game but that is definitely not an easier problem. I got nervous, failed to answer that question and I knew the interview process was over. A couple of days later, however, they send me an assignment to do at home. I put a lot of effort in it (+5h) to be rejected after all without getting any feedback. I tried to get feedback, but they never replied to my emails.
