Interview
The interview process was interesting, they asked me to apply online and after uploding the resume the process took 3+ weeks to get back. Received an email which would ask you to appear for an online assessment test which includes 6 coding questions and 24 aptitude test questions which are simple and anyone having a basic knowledge can easily crack it, not that tough.
