Colloquio
It was not that bad, 3 initial rounds overall okay, it would have been nice if they added some more depth in questions and asked good questions.
and it would have been great if they call or tell something before interview.
A former colleague referred me to the data scientist position, and I was excited to dive in. The interview process was intense, starting with a phone screen that led to a technical round focused on SQL and experiment design. I was asked to write a complex SQL query and design an experiment for a forecasting model. Lucky timing — I had reviewed similar questions on prachub.com during my prep, which really helped boost my confidence. After a final behavioral round, I received an offer and happily accepted.
