There were several rounds which took about 1month of time period. They call you every time for 15-20mins rounds, again & again. They don't disclose the salary or vacancies. It will take about 45-50 days from day 1 interview to get the offer letter. And worst thing ever is the HR department, they don't respond your call or mail. And most disappointing thing is they don't let you know even if u r rejected. They Don't care about your feelings. So if you are going for an interview make sure it is gonna be a long long process.
