Vonage Software Reliability Engineer/DevOps interview questions

Initial Codility test (seemed a bit pointless - wasn't talked about ever again in the process). Screening call with a recruiter (45 mins) and then another technical screening call (45 mins again), which only elicited the information on my CV and tested in the Codility test. They then wanted to schedule another four 45 minute interviews over 2 days, and with no guarantee of an offer I took this as bad vibes and pulled out. They were quick at following up and communicated well, but a poor process.
