The entire process took one month and consisted of four relatively short rounds:

1. A 1-hour standard talk with a recruiter.
2. A 30-minute interview about who you are, your relevant experience, and some follow-up questions (prepare your pros and cons or OCI).
3. A 1-hour technical interview. This was not very difficult, involving typical questions about when to choose specific architectures or technologies, why, and what the associated risks are.
4. A 1-hour session presenting a target architecture and implementation strategy for a cloud migration project, presented in the form of a case study.

Pros and cons of OCI?

Past projects' advantages and involved risks?

When to use data lake vs. Spark analytics vs. microservices architecture?

Lambda vs. Kappa Architecture using OCI data platform services.
