HARMAN interview questions

I had been attended an interview for Harman it was one week process I had 3 rounds (Technical, Manager round, Client Interview) I have cleared everything and I had a salary discussion with HR he asked me to send all of my certificates to initiate an offer letter, they mention one week to process I have waited for 15 days I haven't received any mail or phone call, Later HR mentions we have kept a hold on you. I have put down my papers In my current company , Now I have nowhere to go

Short and good interview, very basis question asked, nothing to worry, HR team was very supportive and timely updates were provided also hiring manager was very helpful, to conclude, you can say that it was good experience
