First Round: The call with HR was good. Second round: 1-1 30 min interview with the Hiring Manager. He did not seem to be interested in guiding or hearing what solution I am offering to open ended database modelling question. He was definitely not engaged and made me feel like I am wasting my time. To the hiring manager: why waste your time and my time if you are not interested from the beginning.

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.
