I met Bloomberg recruiters at the career fair and dropped off my resume. I spoke to them for 5-6 minutes but wasn't sure if they liked me or not. They called me the same day and scheduled an interview for the following day on my school campus.

The interview was a 45-minute technical interview led by two mid-level employees. I stumbled a lot, but they seemed to like me. I got a callback the same day to schedule another interview for the next day. This was another 45-minute technical interview led by two other mid-level employees. I did really well in this interview, and I was called back the same day again to schedule the final interview for the following week, again on my school campus.

The final interview was supposed to be 45 minutes of behavioral interview and a 45-minute technical interview. The behavioral interview was with an HR person and was very short, taking only 15 minutes. Then, the technical interview was led by a high-level employee. The questions were difficult, and I failed to give the correct answer, but the interviewer seemed to like my thinking process. I was told they would get back to me in a week, and I was offered a job a week later.

I was given three weeks to make my decision. They also flew me out to visit Bloomberg before I had to make my decision. Their offer was by far the best offer I received, so I accepted the job offer.

Given a matrix where all columns and rows are sorted, and an integer k, how would you find k in the matrix?
