Principal Global Services, a part of Principal Financial had come to our clg for campus recruitment. The interview process consisted of an aptitude test (conducted by e-litmus on 21st March 2014) followed by 2 personal interview rounds (3rd April 2014). The aptitude test was quite difficult. But i managed to crack it. It took them a week's time to announce the results for the apti. In my first interview there were two panelists. They asked me a lot of questions on my project (Sentimental Analysis). They asked me to draw a flow chart of my project. Asked me about the algorithms used. Then the asked me abt recursive program and asked me to write a recursive program. Then i had done a certification in Business Intelligence so they asked me a few questions on that as well. They also asked a few general questions. My first interview went on for an hour. In the meanwhile a third panelist also joined in to ask a few project related questions. They announced the results for the first round immediately and i was shortlisted. In my second round there was only 1 panelist. She also asked me about my project. Asked me to write a program of fibonacci series. Asked me a puzzle - "There are 27 marbles. all of similar physical properties. Only one of the was different from others. It weighs a little more than the rest. And i am provided with a weighing machine. What is the minimum no of weights to be done to identify it." General behavioral questions were also asked. This interview went on almost for 1 and a 1/2 hour.
