Interview Preparation Tips

Topics to prepare for ZS Decision Analytics Associate interview:
  • Aptitude
  • Guess Estimates
  • Puzzles
Interview preparation tips for other job seekers - For the aptitude test, brush up your knowledge and be quick at answering. For the case study rounds, if you don't know about case studies then learn about it using YouTube videos or read the book Case in Point by Marc P. Consentino (read it for the first time before the case study round, its really good). In the case debrief round, be confident and explain your approach without giving much focus on the calculations, your answer may be right or wrong but it does not matter, your approach is more important to them.

And for the final interview, also called the Evidence Based Interview, prepare for the guess estimates and puzzles as the interviewer will 100% ask them. Be confident and speak out your approach when solving the guess estimates and puzzles as it makes the interview interactive.
