I applied through college or university. The process took 1 day. I interviewed at VinSol (Noida) in Sep 2016
Interview
Average Interview. 3 - 4 rounds.
First Round was Aptitude, average difficulty.
The Aptitude test questions were a mixed set, some were really tough, others were really easy.
Only doing the easy ones was enough if you could identify them.
Second Round coding, easy.
Third Round coding + puzzle. Easy code, Hard puzzle
Fourth Round HR. seemed like a formality.
