I was contacted by Cloudera's recruiter on LinkedIn. First there was a Skype interview with him which was a light chat about regular stuff. After that I have received an online programming challenge from Codility. Then three technical phone interviews followed with software engineers (firstly only two were planned but the interviewer was late from the first phone call and there were a lot of technical problems with screensharing). Then there were three onsite interviews on one day, two with software engineers and one with a hiring manager. Finally, after weeks, there was a last onsite interview with the very new hiring manager too. The whole process took 2 months including the additional administrative stuff (reference requests, etc.) which was way too long. Sometimes the process was really quick and interviews followed each other daily, sometimes I had to wait for 1-2 weeks for the next round and this was very frustrating. Also, a lot of other checks were performed related to my history which seemed a litte overkill to me.
