Quantiphi Data Engineer interview questions

There are three rounds in the interview process :- First round - Assessment round for 15 minutes. Second round - Technical round for 1 hour Third round - Technical round for 1 hour

It was very bad . After 1 st interview the 2 nd round was cancelled just 5 mins before interview and this happened 3 times and they rescheduled it. Also the 2nd interview that happened the person who was taking interview has his room lights switched off asked general questions ended the interview in 10 mins he looked sleepy and disinterested it was just a meer formality . After giving right answers they rejected . Do not waste your time .
