Interview Preparation Tips

Round: Resume Shortlist
Experience: I had a standard resume for this company as per our institute placement cell norms.
I usually changed my “Areas of Interest” as per the company profile. For Headstrong I mentioned subjects that dealt with coding and data structure.

Round: Test
Experience: First round was a written test containing 90 aptitude based questions and the time allotted for the same was 90 minutes. Questions were of high difficulty level; most of the questions based on probability, permutation and combination. 40 people were shortlisted out of the 180 applicants.
Duration: 90 minutes
Total Questions: 90

Round: Group Discussion
Experience: In Group Discussion there were 11 people in my group. The topic for the discussion was the “impact of family drama daily soaps (saas bahu serials) on the society”. Almost all of us agreed to the fact that these serials were sending wrong message to the society. They were interested in students who were expressive. 3 people got selected from my group.

Round: Technical Interview
Experience: The first round was a technical interview. Questions related to my family and areas of interest were also asked though. Questions related to C++ were asked and the topic of data structure was their main focus. They asked me questions on linked list and other forms of data structure. Finally they asked few general puzzles too. This interview continued for around 20 minutes.

Round: HR Interview
Experience: In the HR interview, questions were asked on why they should choose me and why I had opted for Headstrong. They also asked which location I would prefer for the job. They wanted someone who would be comfortable with any location whether it be south or north India. This last interview was small and lasted around 5-10 minutes.
Tips: Preparation of puzzles foe the interview would be beneficial.

College Name: IIT ROORKEE
Motivation: Most information regarding the company was obtained by attending the pre placement talk. The company did not check much about our knowledge related to the company but were more concerned with our technical knowledge.
