First HR, then they told me within 8-10 days I will have a coding challenge. After around 8 days I had to remind through the mail that I have a coding challenge. They replied after 3 weeks after my follow-up mail that I cleared the coding challenge. My next was an online interview with 2 interviewers. The questions were straightforward and easy. Then again they took 3-4 weeks to reply to me back after my follow-up email. Then again after 3-4 weeks, they called me for an onsite interview. and again an online interview after 4-5 weeks. I don't know what they are up to. But, they have really bad bureaucracy.
