parentune Software Engineer interview questions

I cleared the interview process for SE, the process was done in so much hastle that one could easily guess something fishy down there. After the process and even before issuing a formal offer letter, they started asking about my previous salary slips (including all previous appraisals), Manager reference number for verification and other documents. Unethicalism has a limit but they crossed it and even dig inside each and every appraisal I have got in my whole career from the very start, they were doing this in the name of their unique hiring process. At the last, I didn't join this company as to me trust matters. If you can't trust with the details given to you and ask for a documented proof and manager contact number even before giving someone an offer, it is too much.
