Synechron Java J2EE Developer interview questions

It was conducted by ethos HR at Ahmedabad location on Jan 2020. I got selected and they called us to appear for a client interview at Pune office. I got call after a month and issued an offer letter to me. I was about to complete my notice period and they informed me that your joining has beed deferred for couple of months due to corona pandemic. I was jobless because I was not able pull my resignation as they informed me on the last day of my notice period. I asked HR are they sure that they would be able to join me virtually. They nodded at that time, when I called them after couple of months they asked me to find another job. It was worst experience of my life. HRs are behaving childish. They are puppets of client, can kick you out any time. Never put your career on risk with this company.
