Interview prep at more companies
One case each from loops reported at AWS, Palantir, CoreWeave and Microsoft.
4 cases
AWS Solutions Architect
Architecture round, requirements added as you go: a design that survives new constraints.
Palantir Forward Deployed
Decomposition, onsite: a vague problem turned into a plan.
CoreWeave engineering
GPU-fleet design, onsite: one cluster shared by many teams.
Microsoft Cloud Solution Architect
Case study, sent days ahead: a design presented to a role-played customer.
Each case's source tag says which company and role reported its format, how many independent sources describe it, and when. It doesn't mean a company uses our question. Every scenario and number is ours. Preporato is not affiliated with AWS, Palantir, CoreWeave or Microsoft. These cases help you prepare and don't promise an interview or an offer.
