Wooqer IOS Developer interview questions

Interview process was very unprofessional. I had four rounds, first round was a discussion round, second round was a discussion round, third round was DS round and forth round was again a discussion round. First round was quite good as the interviewer was interested in taking interview and also asked good questions regarding process, architecture and what I did in past. But second round was so so, it was with the head and he was keen to know that whether I can write queries for database on server side and asked about my notice period. Third round was good, interviewer was also good. Forth round was taken by the head again and he told me that your notice period is not suitable to us. I asked to him that I have already told you at the starting about my notice period then he replied nothing. Overall conclusion was I had wasted my time in interviewing with them.
