Onsite Technical Round 1
30–90 minMicrosoft process
How to prepare: A data structures and algorithms round prioritizing common patterns like trees, graphs, linked lists, and dynamic programming, with interviewers often providing hints and evaluating how you respond to them.
4
Onsite Technical Round 2
30–90 minMicrosoft process
How to prepare: A round combining coding with basic system design (such as designing a URL shortener) and behavioral questions assessing collaboration and growth mindset.
5
As Appropriate (AA) Round
30–90 minMicrosoft process
How to prepare: A senior interviewer, often director-level, evaluates overall fit, culture add, and technical judgment holistically. This round carries significant weight in the final hiring decision, alongside a mutual assessment of team fit from the candidate's side.
PRACTISE THE QUESTIONS BEHIND THE LOOP
Questions worth rehearsing aloud.
These examples test the kind of clarity a data scientist needs to show. Use them to practise your structure, not to memorise a script.
Clarify the decision, affected users, success measure, and constraints before touching a model. Reframe the request as a hypothesis or comparison that can be tested responsibly.
