Interview
This is probably one of the worst experience of my life in interviewing for a data scientist position. The recruiter reached out me and asked me to study a laborious list of Python, R, SQL, hive, statistics and probability. The recruiter scheduled the phone interview which they constantly kept rescheduling, very unprofessional ofcourse! The interviewer arrived on to call and started with the word "kool" and asked me to open the coderblock. He didn't even care to ask what my name was. He rushed on to the first interview question and asked me a probability question and i gave the answer within a minute. Pat came the reply! Wrong answer! (Even though it was 100% right answer). The interviewer kept pushing me that my answer was incorrect. And he started suggesting me to proceed in his own way and he consumed almost 25 minutes on this. Then he asked me a basic SQL question which he tried to complicate it by not providing the list of values in the table and just complicating that it is tough question. He kept changing his stance on how a record looks and what is the unique key. Then he asked me do you have any questions. He tried to act "kool" as if he has invented the world. I asked him what tools do you use? He kept saying we use hive, python etc and tried to act like he was "uber" cool. I would strongly recommend not to go forward with the recruiting process as you will probably waste your valuable time.
Interview questions [1]
Question 1
Pick up a coin C1 given C1+C2 with probability of trials p(h1)=.7, p(h2)=.6 and doing 10 trials. And what is the probability that the given coin you picked is C1 given you have 7 heads and 3 tails?
The Interview Process is very structured -
First Tech Screening round - 45 mins (usually can extend a bit depending on the interviewer)
- 2 SQL Questions ( Medium to Hard ) - based on Joins
Full Loop - 4 rounds 45 mins each.
- SQL
- Behavioral
- Analytical Execution - stats & prob, A/B testing, case study
- Analytical Reasoning - Case study

Question 1
Questions on Bayes Theorem, Probability distribution, etc.
A friend who worked at Meta recommended I apply, which led to a direct connection with the hiring team. My interview journey included a technical screen focused on product metrics and a behavioral interview. The final round faced me with a practical question about measuring success for a new push notification feature. Funny enough, I had found similar questions in the company-specific prompt section on PracHub, which helped me approach it confidently. Ultimately, I received an offer but decided to decline it for personal reasons.

Question 1
How would you measure the success of a new push notification feature on Instagram? Walk through your primary metric, guardrail metrics, how you'd design the A/B test (randomization unit, sample size, duration), and the tradeoffs between short-term engagement lift and long-term retention impact.

Interview
Completed 3 rounds of the process, which includes the initial recruiter screen, technical, full loop, and team matching.
Couldn't move past the full loop interview. The interview was very engaging, and I actually enjoyed working through the cases. No crazy questions.
