Ho presentato la mia candidatura di persona. La procedura ha richiesto 2 settimane. Ho sostenuto un colloquio presso OYO (Gurgaon, Haryana) nel mese di lug 2017
Colloquio
First Round - On a call:
Briefly interviewed on my previous projects and roles.
Second Round:
Was given a case study on their dummy data set. Had to solve it in 24-48 Hours. It was based on R, Python and SQL along with couple statistics questions. It was based on descriptive statistics though.
Final Round:
Was asked to visit the head office based in gurgaon, and went through three rounds of interview. I was asked technical questions on R, Machine Learning concepts and my previous project experiences.
Then out of never-ending rounds was the final round of interview with the Analytics practice head. Everything seemed fine, but I probably screwed one SQL question and wasn't offered.

Colloquio
Started out good but ended as a very bad experience (WASTE OF TIME). I had 5 rounds with 1 being HR screening round and 4 technical rounds after which I was rejected without any feedback. All of them were pretty good and the interviewer was happy at my answers. Upon asking for feedback multiple times, the HR just turned blind eye and never responded with the exact reason.
After 4 rounds, the HR did not even call to reject you. It was just via email without any specific reason.

Domanda 1
Round 1: Basic profile matching round and getting expectations from both sides
Round 2 and 3 were purely of data science and machine learning fundamentals. I enjoyed as they were more like a generic chat among data scientists.
Round 4 was system design/ engineering round where some fundamental questions were asked.
