The challenge is a unique opportunity for you to put your coding and machine learning skills to test. You will get to solve a real-world data science problem and also get a sneak peek into the kind of problem statements being solved by ZS’s Advanced Data Science team. The offered problem statement is designed to evaluate:

  • your knowledge of machine learning, optimization and statistics
  • your proficiency in identifying the right technique to approach the solution
  • the way you translate the findings from a business context
  • Online Phase (July 19-22, 2019)
  • Offline Data-A-Thon(August 2-3, 2019)

You would be expected to come up with a scalable approach using the provided sample dataset/s. You're free to use any method or tool of your choice and upload your predictions in the prescribed format.

The challenge will be conducted in two phases:

Online Phase: You will be assigned 60 hours to work on the real-world data science problem statement. You will be provided with the past data (Train) and expected to make predictions on the hold-out (Test) data. Based on all the submissions we receive, the top 50 participants will be invited to Phase 2 of the challenge.

Offline Data-A-Thon: The top participants will compete during Phase 2 of the challenge, hosted at our ZS Bengaluru office on August 2–3, 2019. Along with solving another interesting data science problem, you get a chance to interact with our Advanced Data Science leadership team.

PS: ZS will take care of all the travel and stay arrangements for the Offline Data-A-Thon.


Top 3 submissions in each phase will win exciting prizes and a pre-placement interview call letter. Exciting goodies and certificates are in store for all the Top 50 participants.


Final year students from any discipline of graduation or post-graduation/PhD based in India are eligible to participate in the challenge.

If you are an experienced professional, you can still make it to the list of the top 50 data scientists of the country, bag a pre-placement interview letter and participate in our offline Data-A-Thon.
