Eaton interview questions

I had 2 phone calls and 2 face-to-face meetings. I spoke with a recruiter from the company first, then the hiring manager. My first visit was with the hiring manager, HR and another manager from the team. The second visit was with the hiring manager and the Director of Accounting. While it was a little intimidating (they're a very conscious about security), everyone was really nice and easy to talk to. My biggest complaint was the amount of time it took to hear back after each conversation, even when I was given an estimate and followed up. Because of this I ended up taking another offer.

Right away I was contacted by email and an online interview with my possible Team Lead was scheduled. It was good, TL is nice person. If I passed, he said he will send me testing exercise about C++. But 1 month later didnt heard from them (even rejection letter), so it seems a denial.
