      Software Developer Interview

      Mar 15, 2017
      Anonymous interview candidate
      Blue Bell, PA
      No offer
      Negative experience
      Difficult interview

      Application

      I applied online. The process took 5 days. I interviewed at IBM (Blue Bell, PA) in Mar 2017

      Interview

      Took the IPAT, which tests you on number sequences and algebra word problems. The number sequences are irrelevant, and the algebra word problems are timed too short. Some people may disagree and say to study first, but I had other interviews to worry about and did not have the time to study for the IPAT just for one interview. Long story short, I did bad on it (and I was at fault for not wanting to waste time studying for it). Still, I was contacted the following day, and asked to do a phone screen. The phone screen was scheduled for the following day, and consisted of a few fundamental technical questions and some questions to get to know your background. It was a short 20 minute call. Later that day I was invited on-site. Two days later, the onsite happened and involved meeting three people: a developer, the developer I spoke to on the phone, and the manager of the team. Both developers were nice, the manager was not. The first developer I met with had me do some whiteboarding. The first questions was too tough for me to handle, so we did a tree traversal problem to add every node at a certain level to an array. I got about 85% of the question as I was choking after the failure of the first problem. The next person I met was the developer I spoke to on the phone. He asked me only fundamental problems and some basic SQL. I nailed that section. The worst part was meeting the manager. For some reason, I could tell he did not like me the moment he laid eyes on me. He started off by asking me what I knew about C++ and Java. I told him I really only knew Java, and my only experience with C++ was in an intro programming class in college. So he saw the potential in grinding me to a pulp, so he went down that route. After that he began asking me questions on Java, I was able to respond with correct answer, but with every correct answer, he would ask a question one level deeper. It got to the point where he was asking me how I would design a critical component of Java myself, something that I could not even find the answer to on Google. I kept asking him to elaborate on what he meant as I fed him answers he did not like. He kept saying "No. No. I am talking high-level here." He did throw in some fair questions that I did not know the answers to as well. Look, I was at fault for not studying up on some concepts, but when a job is listed as "entry-level" and is looking for a minimum for 1 years of experience, do not expect someone to be able to answer some mid-level questions and act like they are a waste of your time for applying to a job that matched the required skillset that was listed.
