Entrevista
The process started with the PM reaching out in LinkedIn and inviting me to make the process. Then I had a chat with the HR guy and we talked about the company, salary expectations and my background. He was nice at the beginning.
Next step is a bunch of interviews with different people in the same day. At first, the recruiter responsible to schedule the interview sent me an email in the day before with the agenda for the next day without even asking me if I could do it. It's a lot of time and I work from 9 to 5. You can't send an email in the day before expecting people to do it. I told her I wouldn’t be able to join the interview in the next day and asked her to reschedule it.
Then, after properly scheduling the interviews, I asked for half of the day off and still, she scheduled one of the interviews in the morning.
There were 4 interviews: first was behavioral, second was technical (I was asked to make a tree node and search for the leaves), second was technical as well (the engineer asked me to make a function to check the maximum number of boxed we could make with certain requirements) and the last one was an interview with the PM. I expected to be asked only behavioral questions, but he made me an optimization question.
In general, most part of the interviewers were arrogant. One example was the answer one of them gave me when I asked him what was the most challenging thing in his team. He said "there is no challenge, we are very good developers".
Then I got ghosted and I sent a follow up email asking for an update. 2 days later the recruiter answered me saying they would "pass" without any kind of useful feedback.

1 technical phone screen covering basic networking and data structures, followed by a 4-round onsite loop focused heavily on Oracle Cloud Infrastructure (OCI) scale challenges. The rounds were split between low-level system execution, multi-tenant cloud architecture, and standard relational/non-relational database trade-offs. The interviewers kept drilling into network virtualization, hypervisors, and storage layers.
To prep, I needed to brush up on high-throughput cloud networking patterns and storage engine internals. I utilized Apex Interviewer to simulate full cloud infrastructure design problems.
