UST Business Analyst interview questions

Before round 1 I confirmed my notice period is 45 days , then they took 3 rounds of interviews and then said client is not okay for 45 days. Mismangement and fooling client and candidate at it best. Waste of time and leaves

We had a Aptitude test . Selected people were sent to the group discussion. The topic was given by them and we need to talk inbetween the given time. Next round I had only one round interview. That include both technical and Hr. Interview was held on the very next day.
