Infosys Salesforce Developer interview questions

I gave an interview on 2oth nov. In panel there were 2 people, asked technical questions like which deployment tool used, LMS, LDS,some scenario based ques. On 27th hr called me and we had salary discussion. 11th nov I got my offer letter.

Very unprofessional and rude experience. The interviewer turns off camera when he starts interviewing. The manager guy never turns on the camera. They start by asking you to hold your ID against camera like a criminal taking mugshot. The interviewer himself was confused by a lot of topic. Worst of all they dont give any feedback even after months of interview
