Conduent Automation Test Engineer interview questions

The interview process was really very bad. Interview was scheduled at 10 am but my first round was conducted at 4 pm. They did not even provide a place to sit for the candidates. There were only few chairs and most of the candidates were standing and waiting for their turn. So after completing the first round second round was conducted at 6 pm. We negotiated the salary and said they will require some documents which I can send via mail. Its been 5+ months and still I have not got the offer letter. In between I got call from the company thrice during different time that within 1 week they will release the offer letter. ALAS!! I still did not get the offer letter. Sometimes I feel like they are just trolling me. It is really very disappointing, very unprofessional behaviour from the company.
