I applied through university. The process took 6 days. I interviewed at Wireless Federation
Interview
I had a phone screening first, in which I was asked wireless and networking basics. Fairly easy.
I had three separate rounds. The first was HR, which was as expected, good. The second was more of wireless based questions, while the third was focused on matlab and networking. I didn't fare very well on the matlab round, questions were more focused on the production and scaling aspect of things rather than implementation and a general test of coding skills.
Interview questions [1]
Question 1
I don't remember the exact questions as this was more than six months ago, but simply having matlab coding knowledge and no production level know-how will not help.
