Will be giving you few simple tasks to perform on arduino UNO. Sometimes may include basic circuit implementation and aptitude test to check your conman sense. You should apply logic to solve problems and don't mug up the things.
I applied online. The process took 1 day. I interviewed at hIOTron (Pune) in Feb 2015
Interview
There was common process which includes
1. Apptitude
2. Group discussion
3. Technical round
4. Personal interview
Process differences from post to post
But interview process was informed earlier so it was hassle free for me to attend all the round
