As I logged into the Google Meet link for my STMicroelectronics interview, a mix of excitement and nervousness filled me. Unlike an in-person interview, there was no firm handshake or office ambiance—just me, my laptop, and the interviewers on the screen. Here’s my STMicroelectronics interview experience and what you can expect in an online interview with STMicroelectronics.”
About the company..
STMicroelectronics is a European multinational semiconductor contract manufacturing and design company .Formed after the merger of two government-owned semiconductor companies: Italian SGS Microelettronica (where SGS stands for Società Generale Semiconduttori, “General Semiconductor Company”), and French Thomson Semiconducteurs, the semiconductor arm of Thomson ,STMicro claims to be Europes’s largest semiconductor company.
Also this company is known for its good employee culture and lesser layoffs;).
About the author and interviewee.
Hello, everyone. My name is Nitin Dwivedi, and I am currently interning at STMicroelectronics in the VLSI field.Also I am in my final years at J.C. Bose University of Science and Technology , YMCA.
Apart from that I also write articles for WireUnwired and own a Youtube Channel named VlsiBuddy where I teach concepts related to electronics.
STMicroelectronics interview experience
STMicro had visited our campus for intern hiring and I had filled the form , and the selection happened on the resume basis. Basically, they had visited our campus to hire for their DUV team . DUV stands for DRC Unitary Validation. Essentially, it is the team that validate the DRC code by creating QA cells(Quality Analysis) .
So I received an interview call from the team’s lead engineer to finalize the interview process for a position on the DUV team.
My interview was originally scheduled for two days later, but due to unforeseen circumstances, it was moved to tomorrow. So I started preparing for it shortly thereafter. I started revising my notes .
I dressed formal and joined two minutes before the meeting began. It was in online mode .
The interview began with my basic introduction and background information. The first question I was asked was to describe the ASIC flow and explain each step briefly. I provided an appropriate response, and they moved on to digital electronics. I was able to answer all of the questions confidently and correctly.
They then stated that the role is primarily related to Analog , they then asked some Analog electronics questions. I was able to answer those questions as well. They then ask me to draw a low-pass filter and explain why it rejects high frequencies.
Then they began with a CMOS inverter and asked me to draw the voltage transfer curve. Then they inverse the VDD and GND, as well as NMOS and PMOS in CMOS inverter, and I had to explain the output for a given input voltage curve. I used boundary conditions and was successful in solving the problem. They appreciate my approach to problem solving and attention to detail.
Finally, they asked me to write a code to determine whether the given numbers were palindromes or not. I explained the algorithm but did not write the full code, which they were fine with. Finally, they asked me puzzle questions, which I answered correctly.
After the questions, they asked if I had any additional questions. So, when I asked them about the company’s culture and the technology they were working on, they explained everything.
After one week of nervousness and excitement, I received an email informing me that I had been chosen for the job position. I was overjoyed and grateful for the opportunity.
Conclusion:
Entering into VLSI field has become quite difficult now a days especially at Bachelor’s level. But if you have got your skills right you just need one chance.
I hope , this article will come into one’s use (for everyone trying to enter into VLSI field ).
