I got an email long back from the hiring manager about a prospective internship which I declined that time because I already got an offer from other group. However, I kept the mail and followed up recently for a full-time opening with the hiring manager in May 2014 and he said that he actually has an opening now. He asked me to formally apply online for a given job number. In June 2014 I got another email for phone interview which was scheduled in mid July 2014, it lasted for an hour and covered stuff regarding my thesis and prior two internships at Intel. The interviewer was the hiring manager himself and he invited me for an all paid onsite interview in the following week.
Day of the interview:
starting 8 AM in the morning, I had to give a presentation on my thesis topic that lasted for an hour. After that there were 6 one on one interviews each one lasting about an hour (except the 1.5 hrs of lunch time during which I was taken out for a group lunch at a restaurant along with 3 members of the group). The interviewers tested behavioral and technical skills. All the interviews were conducted in the cafe. Pretty informal type. They wanted to see how I think, my problem solving skills, my soft skills etc. There were questions on my published papers (one of the interviewers came with my paper in her hand and asked questions from there) and on my thoughts about dealing with the datasets they have in hand. All the interviewers were very nice and friendly. I got a very positive vibe of the group (consisting of 7-8 members). They mentioned that there will be another person joining the group in August 2014 and if I am hired, I will be their newest member. There were 2 other members who joined last year or the year before, who were about the same age group as I am. All in all, it was a good experience. The day ended at 4 PM with the last interview with hiring manager. Within 1 week I got an offer from Intel HR.
