TATA Advanced Materials Trainee Engineer interview questions

The worst interview process I have seen so far I have undergone several rounds written on technical, aptitude, GD, psychometric test, technical and HR and overall process took 5 months and I am still waiting for the final result every round has a minimum 1 month gap and sometimes 3 months. They don't even answer the phone calls. Better to checkout some other job options. Recruitment team was dumb waste of time.
