I had a friend who worked for the company at that time so I asked her to send my CV for a position we chose on the company site of open positions available only for employees. Pretty quickly I got a phone call from an hr and discussed how many hours a week I can work (as it was an intern position and was supposed to be part-time) and agreed as for the rate (later during the interview with a manager I named a higher amount, and it was ok, so with an hr you can agree on less and raise the rate later during the interview). And later I had one interview with a PM directly, where he asked very general technical questions and standard ones about my previous experiences and where I see myself in the future.
