OodlesTechnologies Associate Consultant - Java Developer interview questions

The first round of interview experience was good but they made me wait for several weeks to proceed for the second round. Also when i got the meeting link for second round , no interviewer joined at that time . I tried to connect with the recruitment team and they communicated that the interview will be shifted to some other day. But I did'nt received the meeting link at that day also and I communicated the same, the HR very rudely told me that the position is now filled. This was a very unprofessional behaviour from their side.
