I was contacted by a recruiter, and then there was the first step: a technical knowledge and coding assessment. I passed this, and then there was a home assignment. This involved analyzing logs and raising alerts according to specific rules.

The funny thing is, the log was not provided. So, I also needed to build something to generate the log.

Unfortunately, my test was rejected, even though the outcome was a bit controversial. The engineer reviewing the test didn't know Java, so they found the application complex and difficult to understand, with insufficient documentation. However, I spent a lot of time testing, providing a UI, and also providing a log generator since the logs weren't provided.

Honestly, I had a bad feeling about it. It wasn't clear to me where to invest time. I spent a lot of time on something that, in my opinion, wasn't adequately considered. Also, the fact that the reviewer didn't know Java didn't help, in my opinion.

I was a bit disappointed by the result, and the recruiter also had a lot of doubts.

Very similar to other big company interviews. Some questions regarding system scalability, data structures, etc.
