Here’s the translation of your message:
Interview with HR: Good, pleasant. Conducted in English.
Interview with the Engineering Manager: Good, pleasant, and engaging. Conducted in English.
Technical Test: A challenge that must be completed in 72 hours. The scope of the task could take an indefinite amount of time. The instructions were poorly explained, and they didn't respond to emails seeking clarification about what was being asked. Despite this, a solution was delivered with a very acceptable design, well-documented, and addressing all the requirements.
Technical Interview: Review of the technical test. Two weeks passed since submitting the test. They expect you to present a project in 72 hours that could realistically take weeks and expect a flawless design, scalable to infinity and beyond, all while following their implementations, which they likely spent months perfecting. The interview itself was very uncomfortable, conducted by a couple of individuals with inflated egos. I’m confident that in a real-world scenario, I would outperform them by far, but of course, they are the "experts." I seriously doubt they themselves could pass the test. This was possibly the worst interview experience I’ve ever had.
In total, the process took 4-5 weeks.
Don’t waste your time; they’re not worth it. There's a complete mismatch between what they offer and what they demand.
