DB2 Software Developer C/C++ - 16 Month Internship at IBM

No Offer – Reviewed May 18, 2013 New

Interview Details After applying online, completing the standard IBM mini math/logic test, got an email about doing an interview in person at the office. This was about 3 weeks after applying. Set a time over email. Interview was about 2 hours, which is a fair bit for an internship position, but then again this was a fairly impressive position. It was a one-on-one interview in a meeting room with a dev from the team, the one that contacted me over email. Had a quick tour of the office before hand. Started off with some behavioural questions. I was nervous, it was my first ever interview for a tech job, and messed them up, starting the whole thing on a bad foot. From there, I was asked questions about my resume. Make sure to really be sharp on all the projects and what not you list, they will ask.

Got into some C questions pretty quick. Some questions about the general fundamentals of the language/advantages. Then some sample code was given on paper, in C, I was asked to find all the bugs in it. Then a few sample coding problems in C with pen and paper. Some fermi or back of the napkin questions after that. It was a lot of flipping back and forth from theory to application to fermi problems. Some questions about OS's, like multithreading, memory management, etc.

Interview Question – I don't recall in particular the coding problems, the interview was sometime ago. Fermi problems can be tricky, but a "correct" answer isn't expected, rather thought process is observed. So for example, one was, how many miles of road is there in New York City?   Answer Question

Linux Developer at IBM

Accepted Offer – Reviewed Apr 10, 2013

Interview Details Had an in-person interview and then was required to complete the IPATO, which is IBM's aptitude test. I had two interviews in sequence -- one with my (soon-to-be) manager, and one with a (soon-to-be) teammate. The manager focused largely on asking me scenario-based questions, while the teammate concentrated on my prior experience.

Interview Question – My manager reviewed the list of skills that I had on my resume and told me that he didn't believe that I had all those skills. This was an internship, but I had about 5 years of prior IT experience as I took a number of years off school to work.   View Answer
