I was contacted via LinkedIn by a recruiter who provided a description of an open position that looked promising. Consequently, I accepted the invitation to proceed with the interview process. The interview consisted of four highly technical stages, covering topics such as cryptography, system architecture and design, C++ internals, and overall candidate experience. In summary, the interview process was challenging, but it was a pleasure to engage with experts in each field. I successfully passed all stages, which took a total of 10 hours, not including preparation time. However, I did not receive any communication from them until I reached out a month after the final stage to inquire about the status of my application. Their response indicated that I had passed all stages but that the position was on hold due to pending decisions from the hiring team, which coincided with a period of significant tech layoffs. Unfortunately, after 10 months, I never heard back from them. It's disappointing because I had a positive impression of the company, but I don't understand why there was no communication from HR, especially considering the substantial investment of time and effort from all parties involved in the interview process.

First interview with HR company with normal HR questions. Followed by the techinical interview with a senior person at TII. I did not had any test, just the technical interview.
