Couchbase Senior Software Development Engineer In Test (SDET) interview questions

time waste + HR is too rude + HR have no idea about company I already had 3 interviews with couchbase panel. Panel was quiet intellectual. But HR at last moment told me to come for the f2f round in Bengaluru for next 3 rounds. When 2 technical + management has only been done. Then again same rounds and that too f2f without any prior notice. As I was not in same city. I was in Delhi. It's pathetic demand from their side. When I said OK will u reimbursement the things, they said yes. First they said over call that all things will be reimbursed, and they didn't mail anything. This is pathetic attitude from the HR. But HR attitude is like they are doing some kind off "upkar" on me by writing in mail that they will reimburse the things. Pathetic interview experience from HR.
