So I had this take home assignment, then a call with one of their reps, followed by a call with their architect, and finally a call with the CEO. Honestly, I feel like they could have skipped a couple of steps, but I get it. It’s tough to really know if someone can code just from a brief chat, so I understand why they did it. The tests and coding challenges were actually pretty fun and challenging, so it was definitely time well spent, regardless of whether I got the offer.

First, I had a take-home test with some MySQL and Java questions to complete within a week. It wasn't too simple. After that, I had a Skype interview where the interviewer mostly explained the role and then gave me two tests to do while sharing my screen. A few hours later, the interviewer mentioned the chief architect wanted to speak with me. In that interview, I was asked a bit about my background and had to complete another screen-shared test on Google Docs. I felt pretty nervous and didn't perform well during that part.

So basically, your recruiters, Mihai Dinu, gave me a Java code assignment about a month ago for the hiring process. It was a huge project that took a lot of time to complete. After sending it to him, he didn't reply to my email or my phone calls. Then, after a month, he sent this email after I sent the project. He said they have a massive backlog due to the high number of applications and will provide feedback soon, estimating by the end of next week. He thanked me for my patience.
Confirmed questions5 questions
- Can you create a Java tool that parses a given log file, loads it into MySQL, and uses a pipe (|) as the delimiter?
- Does the tool accept "startDate", "duration", and "threshold" as command line arguments, with "startDate" in "yyyy-MM-dd.HH:mm:ss" format, "duration" being either "hourly" or "daily", and "threshold" as an integer?
- How will the tool identify IPs making over a specified number of requests within a given timeframe, printing them to the console and saving them to another MySQL table with blocking reasons?
