There are 4 rounds in total and last for 1 month. 1. Phone screen 2. Video interview 3. 1-hr live coding with 3rd party organization 4. On-site interview (product + technical) It's a waste of time, the interviewers swapped twice, and the last time was swapped a few hours before the on-site interview and none of the engineers from the post is involved at the end. I don't know if it is possible that none of the team members was trying to interview a "potential future colleague". Besides, the interview content is randomly assigned. Even though the post is claimed to backend focused, the on-site interview is focusing on React. After investing so much time in a startup interview, they are not willing to give you some feedback, just an email notifying you that you are not suitable for the post. You may get a general answer after further asking and then ghosting.
