There were 3 technical and 1 HR round each one of them for atleast 1 hrs. They took 1.5 months to complete the interview and I cleared all of the round but they did not roll out the offer. They came with me at the end saying that they have decided to close the position and that they are scared (based on their past experiences) that I won't join their company as my expectation is high and they think they won't be able to match it up. I found it very unprofessional to waste theirs and my time for nothing at the end. Hence, i would suggest everyone to think before you appear for an interview with crowdstrike.
