- Q1. What is EM and how we mitigate it
- Ans.
EM stands for electromagnetic interference, and it can be mitigated through shielding, grounding, filtering, and proper layout design.
Shielding: Using materials like conductive foils or metal enclosures to block EM waves.
Grounding: Connecting electronic components to a common ground to reduce interference.
Filtering: Using capacitors and inductors to filter out unwanted frequencies.
Proper layout design: Keeping sensitiv...
- Q2. What is race condition and stuck at zero fault
- Ans.
Race condition is a situation in which the output of a program depends on the sequence or timing of uncontrollable events. Stuck at zero fault is a fault in digital circuits where a signal line is stuck at logic zero.
Race condition occurs when multiple processes access and manipulate shared data concurrently without proper synchronization.
Stuck at zero fault is a common fault in digital circuits where a signal line is ...

Interview Preparation Tips
Experience: Test was subjective and questions were asked from basic analog, digital design, VHDL and VLSI circuits.
Round: Technical Interview
Experience: Had 3 technical interviews each around 25 minutes. They asked me about my summer internship and
questions from microcontroller architecture and its interfacing. Then they asked me the questions
from those problems which I didn't attempt in the written test.
Tips: For electrical students, it might be a bit challenging. I took an elective on Microcontroller in 7th sem which
helped me a lot during the interview. You might want to brush up your concepts of 8085, digital, OPAMPs
and analog
Round: HR Interview
Experience: My family background and my future goals were asked. They asked me about
my internship project and wanted to know what I learnt during the internship. Then I asked a few questions
from them about the company work culture and growth opportunities

College Name: BIT MESRA
Interview Preparation Tips
Experience: They asked me about my thesis and some device related questions as my thesis was on modelling of device. Questions were basic and were related to variation of device parameters with environmental factors and other parameters. Apart from that, several questions related to basic digital circuits were also asked concerning flip flops, latches, setup time and hold time. The technical interview went on for approximately 1 hour.
Round: HR Interview
Experience: The HR round lasted for about 5 mins only. The HR person asked me whether I were interested in going for PhD or not and about my hobbies and interests. Overall, the interviewers are very friendly and asked basic questions only.
Tips: Prepare your CV well, have a good CPI, do your thesis sincerely, concentrate on your basics and you will stand a very good chance of getting selected.
General Tips: Do the courses thoroughly, make good course projects and start preparing for the placement session at least 1 month early.
Don’t ever mention to them that you are interested in higher studies even if you are applying. In case you don’t get a job at your targeted company, don’t lose hope and move on to the next one.
Concentrate on your preparation and the things that are of utmost importance, don’t get bogged down by pressure. Be optimistic and cheerful, because confidence really helps during interviews.
Final Tips :
1. Be confident and enthusiastic in your response to questions because you have to make them understand that you are interested in the profile.
2. Chalk out a plan to strengthen your strong points and address the weak ones.

I applied via Recruitment Consulltant and was interviewed before Aug 2021. There was 1 interview round.
(2 Questions)
- Q1. What is aspect ratio?
- Ans.
Aspect ratio is the ratio of an object's width to its height.
Aspect ratio is commonly used in design and engineering to maintain proportionality.
It is often expressed as a ratio, such as 16:9 for a widescreen TV.
Aspect ratio can affect the visual perception and usability of a product.
It is important to consider aspect ratio when designing graphics or layouts for different devices or mediums.
- Q2. How do you decide stackup?
- Ans.
Stackup is decided based on the number of layers, signal integrity requirements, and manufacturing constraints.
Consider the number of layers required for the design
Evaluate signal integrity requirements and impedance control
Take into account manufacturing constraints such as minimum trace width and spacing
Balance cost and performance
Use simulation tools to optimize the stackup
Consult with PCB fabricators for their reco
