I got an email from a recruiter asking for my availability for a phone interview. The phone interview went well, and the hiring manager liked my background and invited me to a group interview. They were very flexible with scheduling and kept me updated. The group interview started on time and included questions about software and hardware skills. Everyone I spoke with was pleasant. They started with casual conversation before diving into questions. The questions were generally easy for me since I'm in the field, but one person, the head of development, asked some tougher questions. Overall, it was a good interview experience with Dolby. I learned some new things and would have liked to join them. Sadly, I didn't get the job; they let me know a day after the expected 1-2 business day reply, stating they found a better candidate. I'm still interested in working with them because it aligns with my passion for video and audio engineering.

Technical Behavioral Presentation
The interview day kicked off at 10am and wrapped up around 4pm. I met with six different groups of employees throughout the day in a meeting room. Lunchtime also turned into an interview, this time with technical writers. Everyone I spoke with was a senior or staff engineer, including a project engineer, an engineering manager, and a team director. The final part of the process involved an HR representative giving me a rundown of the company benefits and perks. They also showed me around the company's gym and cafe before my interview concluded.

Technical Coding
It was a two-part video interview process. The first part was around 20 minutes, and the second part was much longer, about 1.5 hours. They asked a lot of technical questions, including some coding challenges. It seemed like they were specifically looking for candidates with knowledge of hardware devices.

Quoted word for word from Dolby interview reports.
“About quantization and sampling in DSP: Given that the human hearing range is 10Hz-20kHz, why do we utilize sample rates like 44.1kHz, 48kHz, or even 96kHz for digital media?”
