Ray Business Technologies Senior Software Engineer NET interview questions

There was no interview. I got a mail for Phone Interview. On the day of the interview I didn't get any call. I called back Ray 3 -4 times and was told each time that I would be called back. Didn't happen. I called the next day and got a confirmation mail for another phone interview. Again didn't happen on that day. Called them and was again told that I would get a call back soon. Didn't happen. So no interview, no offer and highly irresponsible behaviour on HR/Recruiters/whoever.
