OodlesTechnologies Java Developer Associate Consultant 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.
