NXP Semiconductors Interview Questions /  NXP Semiconductors Interview Experience 

NXP semiconductors first shortlisted the candidates based on there resume. company shortlisted near about 40 students for each software and hardware profile.

Fist round  of NXP was online test which was of 90 minutes and consist of mcq and 3 coding questions. the test of was on the talent decrypt platform and it was fully proctored. Near about 40 mcq questions were asked from aptitude, os, dbms, digital electronic, computer organization, c, c++, algo and ds. among the 3 coding question 1 was simple, one was moderate and 1 was hard. i was able to complete 2 coding question. based on online test company shortlisted 9 students for software profile.

NXP had only one technical interview of 90 minutes. for each candidate the interview was taken by a panel of 3 member. interview started with my introduction and then panel discussed my projects . they also did some basic cross questioning on my projects. after project they asked me to rate myself in python,c and c++. since i rated myself more in c++ , they started asking questions on c++ for example virtual destructor, what is the size of objects of empty class , discussion on different data segments of memory in c.

Difference between heap memory segment and static memory segment. memory leak was also asked and how i would control it. they also asked how i can implement garbage collector facility in c++ as it is provided in java, just a logic. they asked me how i would handle infinite loop in program ie if a program contains a infinite loop then it should not fall in infinite loop, i should be able to halt my machine. after c,c++ the panel jumped into OS.

OS Interview questions NXP They asked me what is difference between program and threads. why we use threads. how can we control race conditions and data inconsistency. how threads communicate between each other. does actually parallel processing happens in multicore processors or we just gets a notion that processes are working parallely.some questions on semaphore and locks. after OS sections they asked me which i would give more importance to , project development(writing code) or testing while working on real time project.

And finally the asked to write one program and explain it. programof NXP : given a number n , a bool direction(can be right or left) and a number k , i have to rotate the bits of number by k in given direction and have to return a modified number. i completed the code and explained it to panel ,they approved my logic and asked me to optimize it and then i explained them the optimized solution.

After technical round ,a HR telephonic interview of  NXP happened. they asked about my family background , myself and asked me to explain my major project. they asked me what u know about NXP semiconductors, who are the competitors of NXP semiconductors. and finally asked whether I am ready to reallocate or not. Finally company selected 4 candidates for software profile.

DO Must Do Coding Questions form GFG, Interview Preparation Ravindrababu ravula videos, OS and CN are Important subjects for any interview, I revised the same from Ravindrababu Ravula’s GATE videos. If you have time, You can prepare DBMS thoroughly otherwise SQL,Normalization, Indexing, E-R would be enough. Prepare your Resume wisely and properly.

Interviewers can ask you the questions on OS, Computer organization. Just be strong with your basics whatever they will ask you will be able to approach towards it for sure. Interviewers were very supportive and they were also taking part in my approaches to the problem like a discussion.

NXP Semiconductors Interview Questions /  NXP  Interview Experience 

There were 4 rounds. The first round was a screening test. The test had 27 questions in total. 20 of which were MCQ, 2 were design questions related to state diagrams, and 5 were short answer types. There were only 2 analog questions 🙁 and the rest were based upon different topics of digital electronics.

The Second Round was the first technical interview. They asked me to introduce myself. I said something and then ended by saying that I am more interested in Analog. They started the interview by asking 2 questions from the screening test, one of them was based on Pipelining and the other was about the function of the JTAG programmer and the role of RESET on the programmer. Then they asked me about Stack pointer, Link pointer, and about DMA. After this, they asked me about Metastability and STA(Why setup/hold ..How to correct the violations) and then they ended the interview by asking how to compare 2 8-bit numbers. I used some intuition to answer the questions related to uP and comp. arch.

ANALOG  NXP INTERVIEW QUESTIONS The third round was an analog interview :)) .

Output stages, their relative comparison.

RC LPF and HPF. Why biasing? How to bias?

Working of CMOS inverter and Schmitt Trigger were the questions that were asked to me in this interview. This round was better than the previous one.

The final round was the HR round. It went on for about 30mins. Why you? Why NXP? Why Analog and what if you get a digital profile (Answering this was fun)? What if TI or Qualcomm offers the same job with a higher package(this was funnier XD)? were some of the questions that were asked to me

HOW TO CRACK NXP SEMICONDUCTORS  SOFTWARE ENGINEER INTERVIEW??

I studied digital basics from C.H. Roth. STA from the Vlsiexpert blog. (According to me Clock skew is more important than other topics, the same person has a youtube channel too. I referred a playlist for there to study about the Clock skew). I did not study pipelining (I had not answered the pipelining question.) You can read about the Output stages from Razavi. (if you have some doubts please don’t hesitate from mailing him. He replies back to your emails(he replied to some of my emails). You will find the email address on google). For OpAmps I referred Sergio Franco. Although I didn’t study them I would suggest you to study computer architecture, Pipelining and microprocessors very well. PS: Exchanging the input terminals of general OpAmp ckts and predicting the response helped me a lot to know more about OpAmps.

NXP is one of the developing companies in the semiconductor industry. While attending the pre-placement talk I got to know that they are working on LIDAR, RADAR, ADAS, and many other hifi communication terms were there. (ECE peeps who are interested in communication can give a try). You can actually get an interview arranged for the domain in which you are interested. The interviewers who were assigned for our college were (okay if not all then most of them) for digital domain. One of panel members who were assigned to me actually hinted that I will get an analog interview later on…..which did happen.

FAQS OF NXP

  • Is NXP a good company to work for?

No doubt NXP is a good company ,the work culture you get here is the best and also for the freshers it is the best as you will learn a lot from her and the growth is awesome.

  • How do I get placed in NXP Semiconductors and what are the key factors? Also, do they put a lot of weightage on the CGPA?

Before coming on the placement thing first I would like to tell you about the cgp criteria. Actually it’s different in different institutions. But I would rather say have your CGPA more than 8 or 8.5 which puts you on the safer side. Our case the cut was made at 8.5 first and then revised to 7.5.

I can tell you about the broader perspective. The CV that you carry has a lot of importance. The summer training that you do and the projects you have worked upon is important. It’s not important to have done lots of project but even if you have done something you should be knowing what you have done. So if the interview that you have is of 40 minutes, out of that 20 min are for these things.

  • Selection procedure of NXP 

They conduct a paper of about 1:30 hour which contains questions regarding digital circuits, STA timing Analysis (must), basics of opamp,analog, state machines, computer architecture etc. Complete those questions first which you know you can do. And then do the ones which you don’t know. It’s important because at the time of interview this sheet will be in front of you and they will be asking you how you have done that. Also those questions which you do gets wrong, they guide you to do that. Thus checking whether you learn quickly or not which is the essential part of interview.

Try to have your basics cleared and everything will go just fine.
