The selection process consisted of a total of 6 rounds, 1 online assessment, and 5 interviews.
Online Assessment Round
3500 people applied for all three roles combined and got the link for the online assessment. OA was different for different roles. I will be specifying about the DS role. There were around 20 questions - MCQ questions based on English, aptitude, SQL, and Python, 1 SQL query (medium), and 1 ML problem ( dataset was given, we had to code in Jupyter notebook and submit an output CSV file with our prediction value).
~1100 were selected for 1st interview round. The interviews were taken in groups. My interview was scheduled for the third week of August.
1st Round: Technical (1hr 30 mins)
- Some basic questions on Python, pandas, and matplotlib - codes

2nd Round: Case study
- happened just 15-30 mins after the tech round
- The same interviewer asked a case about whether we can open a Cafe business given certain details and what strategies would employ to ensure sales during the starting period.
- Follow up on how to increase profit once the cafe is established.
3rd Round: Stakeholder round (HM)
This round was scheduled on the next day of the case study round. 30 min asked in depth about projects, then asked why data science. What does a Data scientist do? What kind of work do you want to do and asked something like a case, but more technical, like giving consumer goods data with an overstocking issue what steps could be taken, and what data would be needed.
4th round: ION day (Noida office) culture fit
- The travel and stay was arranged by the company.
