Excers interview questions

Worst interview process, they have taken written test after qualifying that round they ask to come office for face to face interview there again they have taken written test and after that next round was face to face technical interview in which mostly questions asked related to SQL. After qualifying that round they asked to come next day for interaction with Director but after sending lots of email they have given time for final round which was on 06.08.2019. I have given interview to director then their HR team said to me , you have done well and we will provide offer letter but from that day till now they didn't informed and I think Excers does same thing with most of the candidates. They just waste your time. They have completed all rounds of interview and never send me offer letter this shows how they kill your precious time. Except this I haven't saw any other company doing so.

At first they conducted the aptitude test in my college, there is five sessions of questions, In that the first part on aptitude, and some questions on reasoning, and C++ programming questions, and java programming questions, and some questions on SQL queries.
