It started with an initial personality interview. Basic questions about some past experience and some things on my resume. After that the second round consisted of a questionnaire. The questions were typical hardware related questions. Also more in depth questions related to experience. After that there was a 3rd round interview which was the technical interview. This consisted of more questions related to my resume and prior experience. 4th round was an in house interview. You meet up with HR, they go over a couple more aspects about the company and a little bit of detail regarding compensation as an intern, and then you are given a quick tour of the office. After this you are separated from the other people applying to your position and given a room to your self were you have 3 more short rounds of interviews. The questions were fairly similar throughout but was asked for more specific answers throughout the day. Overall everyone is extremely polite and pleasant to talk to. When they say business casual and no suit or tie is needed they mean it! This is a very business casual/casual work environment attire wise due to the nature of the firm. Overall it was an excellent experience and am glad to have my first internship here.
