Candidature

Le processus a pris 1 jour. J'ai passé un entretien à NVIDIA (Santa Clara, CA (États-Unis)) en mars 2011.

Entretien

You will get 2 or 3 phone interviews for one position. Those who performs good will be invited to on-site.
The phone interview is not difficult, something like basic exam questions.

Questions d'entretien d'embauche

• Draw a two-put NAND gate and size it, assuming the ratio of PMOS/NMOS is 2 in inverter. Then suppose two input are A and B for NMOS and PMOS. A is close to output and B is close to ground, input A change from 0 to 1 at t=t1, input B change from 0 to 1 at t =t1 (t1 &gt; t0). Describe how the output change. Then input B changes from 0 to 1 first then input A changes from 0 to 1. Describe how the output changes. Are there any differences between these two scenarios?   4 Réponses
• How to modify a two-input NAND gate to an inverter?   4 Réponses
• You are give two flip-flops and there's an combination logic in between, the two flip-flops are driven by the same clock. You are provided with parameters of T_reg, T_logicmax, T_logicmin, T_setup, T_hold, etc. How to determine the cycle time and hold time of this circuits.   3 Réponses
• Draw an inverter. Then switch the position of NMOS and PMOS. Describe the circuit.   3 Réponses
• You are provided with one XOR gate, one OR gate and one NOR gate. Please build a NAND gate.   4 Réponses

J'ai postulé via un établissement de l'enseignement supérieur ou universitaire.. Le processus a pris +4 semaines. J'ai passé un entretien à NVIDIA.

Entretien

There was 45 min technical phone interview scheduled after I received invitation email from Nvidia. The interview starts with the interviewer talking about his group's responsibilities and general information about how different groups inside Nvidia interact with each other.

The questions remembered so far are:
Setup time and hold time analysis: specify which part of a circuit contribute to the setup time or hold time violation?
super buffer: given a load capacitance, how to size inverters so that the overall delay would be smallest?
simple logic design: how to convert a two input nand gate into an inverter?
...
can only remember these questions so far... good luck!

Send my resume and did a quiz in the career fair. Got an email asking to set up a phone interview about 7 weeks later. The second phone interview is setup very quickly after the first interview. 2 phone interviews so far. Do not know whether there will be an onsite for internship.

Questions d'entretien d'embauche

• What's power gating and clock gating. Briefly explain setup time and hold time violation. Briefly describe what is physical design. Sequence Detector. And some questions about my project.   5 Réponses

Entretien

I had applied on the company website and got a call about 3 weeks later. I was contacted by a HR executive first and then the interview was set up about a week later. The interviewer was the manager of the physical design team at NVIDIA. The interview started off with a brief intro of the team and their work, Then he asked a few questions on my projects and some basic VLSI concepts

J'ai postulé en ligne. J'ai passé un entretien à NVIDIA (San Jose, CA (États-Unis)) en mai 2017.

Entretien

My application position mainly work on the synthesis part. I got 2 phone interviews, the questions were all the tech Q. Those were really easy. Then I quickly got an onsite interview from 1:30pm to 5:30pm to be interviewed by 5 engineers. 3 of them ask Tech questions which were easy to answer. Manager mainly ask me about the personality question. I did not give a good answer in the personality part.

Questions d'entretien d'embauche

• how to solve setup violation? What the solution would impact on the other part of the design?
how to deal with the SI issue?
Clearly know about the calculation of setup time, or min clock period
What is OCV on timing check？how to calculate? What is the CPPR?   3 Réponses

Very bad. They never really got back to me even after I tried getting to them. I told them why is my third phone interview cancelled but they never got back. Overall experience was very bad. Recruiters are not good.

Entretien

one phone interview
he was a lead of physical design
explained his work and on what they are working on like clock synthesis, APR.
He asked some basic layout questions too.
Overall experience was decent. I expected a positive response, though i didnt. Gpa might be a factor in filtering out in initial rounds

The interview was hold during the info session. We talked about my previous projects and experience. Then they asked some technical questions. The question was not difficult but if you are a student as me, you need to review the basic stuff.
