Genpact Devops Engineer interview questions

There were 100 people for the Interview, we had only one round of interview since there are too many candidates. I was told I'v been selected in the process after finalizing the Salary the role, I was told I will get the offer letter and I didn't get and When I tried calling HR there was no response for a week and finally drops email saying that Positions are seized for a month. Then I waited for 2 months I'm not sure if they gave such a silly excuse after providing an offer verbally. Total waste of time.
