Computer Power Group interview questions

First round was JAM, the HR were friendly and were quite open with us. But the session was unplanned, they were interrupting people and adding few more points for them to discuss. It's like they just want to hear the word 'learning python' , they completely forgot about the people who've spoken first and they had little content to talk about and ultimately all the capable people who spoke in the beginning were ignored

i got a call from the hr for the interview then i went for the interview and i selected for their client project after that salary discussions also completed.. the hr told me that the immediate joining i said ok but its already 1 month completed till now am not getting offer letter and am calling so many times to know about my offer letter but they are not responding to my call..
