Anonymous Interview Candidate in Los Angeles, CA
I applied through college or university. The process took 1 week. I interviewed at Ambarella (Los Angeles, CA) in Feb 2017
I got contacted by Ambarella HR one week after I submitted my resume at school career fair. I was scheduled to talk with a senior engineer from the ASIC design team. He started with general questions about my resume, went into details of several projects I listed. Then he began to ask technical questions about Verilog basics, bits operation, digital circuits and etc. The question is very basic but covers a lot. The guys who talked to me was very nice and patient that he would guide me through the thinking process when I got stuck at his questions. Although I managed to answered most of his questions, I did't feel I did good enough to get the job. After my first phone screen, I had not heard from them EVER again. I did not receive any email regarding my application progress nor did I get any rejection letter. Neither did the HR replied to any of my email ever since. Such irrespective attitude toward their applicant reflects their company culture from my personal opinion.
- What's hold time and setup time? When does setup and hold time violation happen?
- Please specify three ways to solve setup and hold time violation and how would you implement your solutions in verilog?
- What is the difference between blocking and non-blocking operation in Verilog? When will you use them?
- How would you build a sequential block and combinational block in verilog? what will you use "always@ * "?
- How would you build a 4 to 1 mux with only 2 to 1 mux modules?
- Give me the number X in its two's complement form.
- Tell me whether this sequential block is synchronizes or asychronized.
