  • Business Scenario – To me, he gave a scenario that Uber is already operating in my densely populated city. Will it be beneficial for Ola to start its operations there and what challenges Ola will have to face if it decides to start its operations in my city. Answer this scenario with few assumptions related to – the population of the city, demand for cab in the city, market share of Uber, ways to kick start the operations of Ola, and the annual cost that will be incurred on them, will they be able to recover these expenses. NOTE: you can take any definite assumptions, they are only interested in your approach and intent. I was given 20 minutes to think about this question.
  • Lastly he asked me about an instance when I had conflicts with team members and what approach did I follow to solve this.

TIPS – Answer all the questions with confidence and for business scenario answer with assumptions, facts and figures and a good approach. They are not looking for good or correct assumptions. They are only looking for your approach and intent.

Finally 24 students were selected for BTSA role in ZS and I was one of them.
