Interview
The process took over 4 weeks. I applied through a friend's referral.
Following were the rounds (for anyone who is preparing):
1. Telephonic round: little over 30 minutes over a phone call assessing overall fitment, more of a screening round. Asked about my projects, my role & experience followed by a case study (Customer churn problem)
2. Problem solving round: Couple of case studies and a math puzzle
3. Data handling: Entirely on SQL, joins, window functions and other simple select statements. You dont need to know all syntaxes you can also write a pseudo codes and explain your process flow. Followed by a database schema round (Had t explain what kind of tables and unique keys in them would i have if i was to create a database for Bengaluru road transport)
4. Analytical solutioning: Similar to problem solving round but more detailed in nature
5. Overall fitment: Cross section of previous round and some behavioral questions
6. HR: 30 minute round. All of them behavioral questions.
Tip: Be very active during all the interview rounds, its okay to make mistakes and give wrong answers but explain what you were thinking and why you thought that might work.
