Telephonic interview was scheduled after an initial chat with their HR person. I didn't get any call from the interviewer on the said date, and the HR neither bothered to respond to my e-mail about the reasons for the cancellation of the interview nor did he call me to reschedule the interview. After two days, I called the HR, who, though was unapologetic about the mistake, agreed to reschedule the interview to a different day.
I had an even more horrible experience the second time. The interviewer called some 15-20 minutes late for an interview whose duration was 30 minutes, and then wound up the interview within 5 minutes. The interviewer was completely clueless about the position for which he was interviewing, and asked completely irrelevant questions. It appeared as if he had just woken up from his sleep, and was in a hurry to go back to sleep. He didn't even bother to understand the work that I had done in my previous companies, and also did not give me any opportunity to ask any questions.
It looks like the company is filled with irresponsible people who do not value others' time. Some of the employees need to be seriously taught about the proper usage of calendar and clock.
