Persistent Systems interview questions

It was campus placement opportunity.First round was online assessment,Then there are two technical interviews which includes Oops questions,DSA questions on array,String,LinkedIn list,Stack.Then final round was HR round.Hr round is Non elimination round

The most deceiving experience I ever had with a recruiter! The process was slow, incomplete ( the whole information wasn't provided by the recruitment agency), unserious, untrustful and unprofessional! They made me a formal offer stating that their end customer (I was interviewed by and they seem OK) by email but then they did not respond anymore when asking them to send me the written ofer, either by telephone (they provided me a wrong number) or email. After several emails to them, they bothered to reply and told me they will try to shorten the notice period and the first day of work with them, would be July 1st, 2024. I never heard anything from them ever since (one month and something).. Stay away from them, they promise great things, they do not do it!
