I applied through an employee referral. The process took 2 days. I interviewed at Energy Alternatives India (Chennai) in Sept 2013
Interview
For an internship, you will have a mail with the CEO or either of the employee's. Interview might ot might not happen for an internship. I didnt have an interview because i went in with a friend of mine, so i was asked the basic questions about myself. Its a fairly easy interview process.
