Binary Informatics Senior Software Engineer interview questions

2technical rounds along with 1 HR round or managerial round Company don't have any ethics I have been give offered but when it comes to salary negotiation part they didn't provided the amount which was my expectations even they stop picking your call They took my all documents with them my salary slip my bank statement each and everything and now they are not responding my call neither giving reply on mail Worst management system here is.

The process was quite easy and smooth. Decisions are conveyed instantly and with feedbacks. The interviewers are skilled and explained the job description pretty well and the expectations are also realistic, seems like they know what they are doing
