There were a couple of steps in the process. First culture fit, then a technical test. Both were fine in my opinion. People were nice and interested. The technical interview was quite difficult.
A entrevista consistiu em um teste técnico online com algumas perguntas tecnicas do hackerrank que deveriam ser respondidas em um periodo de tempo predefinido (acho que dentro de 1 horas).
Feeling thrilled to have accepted the offer, I look back on this interview process as both challenging and rewarding. It began with a technical round where I tackled a complex A/B testing design question, followed by a SQL query on user retention. The final stages included a system design discussion that had me sweating, but honestly, the system design section on PracHub prepared me well. Each step pushed my limits, but the culmination was definitely worth it, landing me a role at Microsoft.

Phone screen with HR/recruiter. Less than 10 mins. Very basic mostly about role fit and my background and resume. Did not hear back from them at all. Very unenthusiastic during the call
