Interview Preparation Tips

Round: Test
Experience: There were some basic questions on probability theory, digital communication (mainly wireless communication, like problem on GSM, CDMA, and OFDM). Some questions were from DSP (like DFT etc.). Basics of information theory (EE 624) should be clear; there were some questions on calculating capacity of a Gaussian channel, differential entropy etc. A single problem from C programming was there and it was very simple.
Two sections : 1) VLSI 2) Communications

For VLSI stream we had to solve only the first section.

Type of questions and details :
Questions were a mix of digital and analog.
Most of the questions were on digital logic design.
1) Given a current mirror circuit we had to identify and calculate what is the current through one MOS Transistor.
2) Question on timing analysis-setup time, hold time ----this very important---you have to be very clear in this concept. Frequently asked.
3) Question on Op Amp. It was an integrator …had to calculate output voltage.
4) Many questions were on logic design.
5) Questions on devices like if doping increased, how would the other parameters vary..?
Duration: 60 minutes
Total Questions: 30

Round: Technical Interview
Experience: View 1: He asked me most of the questions on my thesis and my previous projects and term papers (related to wireless communication). I was also asked about viterbi decoders, OFDM and MIMO (my thesis was on MIMO).
View 2: Questions were mostly on timing analysis.

General Tips: One should try to keep himself focused during the whole time of written test and interview. Basics of probability theory and communication theory should be very clear.
Skill Tips: Be well prepared with both digital and analog. You must know Verilog.
Skills: Probability, Coding, Information Theory, Wireless communication

Round difficulty - Easy

The interviewer asked to put everything on the blackboard and write down the code of each and everything.

Question : Explain all the search algorithm you know with space and Time complexities. 
Answer : Linear search : It is a sequential search algorithm where the entire array is traversed till the desired element is not found. Time complexity is O(N) and auxiliary space is O(1). 
Binary search : In this algorithm, a sorted array is searched by repeatedly dividing the search interval in half. 
Steps : 
1. Initially the interval covers the whole array.
2. If the value to be searched is less than the item in the middle of the interval, narrow the interval to the lower half. Otherwise, narrow it to the upper half. 
3. The process is repeated until the value is found or the interval is empty.
Time complexity is O(log n) and auxiliary space is O(1) in case of iterative implementation.

Myntra had conducted a coding test on campus before the start of the placement season with 2 questions, one on stack and other on DP.
Tips : For the test, the DP question asked was pretty standard, on Longest Common Subsequence. The question on stacks, I don't remember what it was but it was also pretty straight forward. For the test, I would recommend to solve problem from GFG. If they do come to resume shortlisting, they are looking for people who have done good projects and internships.

The interview started off with questions on my general interest in Software Development. The first round had two coding questions, I was supposed to write the code on paper. 
For the questions, they asked me to code the solution first. And then gave a specific input and asked me to demonstrate step by step in my code, how it would lead to the correct answer.
Tips: It's ok if you can't code a general solution, if you can write a code which works for the particular input they have given then also it's ok with them. But be thorough with Data structures.

Round 3 - Face to Face 

(3 Questions)

Round duration - 60 minutes
Round difficulty - Medium

I wasn't asked to write any code in this interview. They asked me some questions on Machine Learning, because of my projects in them. Then they asked me if I knew graph algorithms. Since I knew BFS and DFS, I told them. They asked the difference between the two. Then they asked me if I knew how to find the shortest distance between two points in a graph. I didn't know Dijkstra's properly but I knew it worked on the greedy approach so was able to tell that. Then they asked me how would I find the second shortest path. I tried to answer it with the same greedy approach, but couldn't arrive at the complete solution.
Tips: They ask a tough theoretical question. It's ok if you don't know the answer, they only look for your approach.
