### Round 2

It is an Interview Round, the panel consists of three group members namely Technical, Managerial and HR. You must know each and every bit that you’ve written in your resume.

First, I was asked about my low score in Bachelor’s ? (I didn’t expect this) In defense, I answered them that I was involved in many Extracurricular activities and then we talked about my extracurricular activities, about my experience and their impact. This went on for around 12-15 minutes.

Meanwhile, the person from the technical department was visiting my resume and he asked me to explain in detail about my internship project which followed by questionnaire regarding it.  We discussed various key scenarios of the project after that. He also asked me about concepts of OOPs, some language based questions, questions on trending technologies etc. This went for around 25-30 minutes.

HR representative asked me about the areas I would like to work on and why did I chose those areas. He also asked some questions from resume. This went for about 10-12 minutes.
