I applied through an employee referral. The process took 1 day. I interviewed at Cypress Semiconductor (Bengaluru) in Aug 2018
Interview
Three rounds, the written mcq round, and two technical rounds. There were around 350 people and after the written round, there were like 170 in the shortlist. After first round of technical the shortlist went down to 23 people. After the final round, 17 people were hired, and sadly i was among the 6 people to not get selected
Interview questions [1]
Question 1
Basic electronics , problem solving and your projects
I applied through university. The process took 2 days. I interviewed at Cypress Semiconductor (Bengaluru) in Sept 2020
Interview
I got the interview opportunity via a campus placement opportunity at my college. First, there was a written test consisting of Aptitude, C programming, and Electronics based questions.
After that shortlisted people had 3 Technical Interviews and 1 hr round, each round being an elimination round.
The Interviewers were polite and checked your basic understanding and knowledge.
Interview questions [5]
Question 1
They asked firstly about the project done in the Embedded field like projects based on Microprocessors and Embedded C projects. And went in-depth regarding the same.
1) Tell me about yourself
2) Describe one of your projects. Then he spent about half an hour over that project asking questions about hardware! software, libraries, etc.
3) Difference between macro and function.
4) Define a macro for a maximum of 3 numbers. Optimize it. Gave some cases to dry run them.
5) Code to set the 20th bit of an integer.
6) Storage classes
7) What is static variable? Where they are used? Why it does not change it's value?
8) Static functions
9) One static variable is defined in file.c.Call it in another file2.c (I didn't know answer of this question but after this interview I googled it and then this question was asked to me again in second interview)
10) Function pointer and their use. Declare and call a function pointer.
11) Difference between structure and union and structure and class.
12) Code for nested structure and call it.
13) Time complexity concept.
1) What is a flip flop?
2) Do you know DSP. What is Fourier transform?
3) Difference between const*void ptr, void const *ptr, const void*ptr. Or pointer pr bhot ghumaya kiya isme esa kru toh kya hogaa , is pr ++ kru toh kya hoga etc etc.
3) Storage classes.
4) Tell me about internship work. As my internship was related to networks he asked me some questions on the OSI layer etc.
5) UART protocol, header frame, baud rate, etc.
6) He asked me if I have worked on UART
Some nontech questions to know my interest.
Difference between C, C++, C#.
2) 8051 vala project explain kro
3) Assembly language k konse konse instructions use kiye the? Fir koi bhi random ka syntax or working puchi.
4) Difference between RETURN and RETI.
5) Puraa interrupts, working, IE, IP and timers etc. IVT, ISR etc.
6) ports of 8051 and uske kam.
7) PSEN nad ALE ka kam
8) Interfacing of external memory with 8051.
9) Or bhi bhot sara 8051 pucha von neuman, register banks, serial communication.
10) difference between micro controller and processor. He also asked me ki which books did I study for 8086 and 8051.
1) Wired and wireless networks
2) if wifi exists then why Bluetooth. What do you think?
3) Explain your favourite C program.
4) Why cypress?
5) What do you think will you be able to pass this interview?
6) Library functions of Arduino.
7) Your favourite programming language
8(Why not masters?
