The process took about 3 months, the process started with an online coding challenge on hackerearth, the shortlisted candidates were called for an offline hackathon at Bangalore. This wasn't originally a hiring event but that's how they select freshers for hiring.
After a few days, I was contacted through correspondence, the mail consisted of a cocubes test link and a hirevue online interview link.
The candidates shortlisted through this test were called for a face-to-face interview at the Bangalore office.
