Branch:
Electrical and Electronics Engineering
Session:
2022-2023
Offer obtained:
FTE
Description of role:
NA
Job/Intern location:
Bangalore
Eligible Branches:
B.Tech, M.Tech - CSE, ECE, EEE
Eligibility Criteria:
CGPA - 7 and above
Selection Procedure:
Round 1 - OT
Round 2 - Technical Interview 1
Round 3 - Technical Interview 2
Round 4 - HR Round
Description of Online test:
The test consisted of 27 questions in total and 135 min to complete the test.
All are MCQs.
Since it is a digital design engineer role mostly the questions are based on duty cycle, flip flops, registers, static timing analysis, faults, CMOS circuits and Combinational logic.
There are 4 simple coding questions.
Description of Technical Interview:
Each technical interview is for 1 hr and every shortlisted candidate will have 2 interviews
Technical Interview 1:
Mostly focused on the basic circuit design using gates, finding set up and hold time and designing circuits with f/3,f/2 frequency at different duty cycles.
Some questions on Finite State Machine, Static timing analysis and Flip flops.
Analytical questions are also asked to test your thinking skills.
Technical Interview 2:
This interview started with reasoning and aptitude questions. Questions are displayed, and we have to answer them.
Later questions on digital circuits were displayed which involved identification of fault and hazards, a problem on clock period, changing f/3 circuit to f/2.
At last a question was asked to implement a dice such that a random number from 1-6 comes after its thrown. The interviewer asked to do it in a general logical way or using digital circuits. I came up with a circuit using flip flops and register.
Description of HR Round:
This was a very short interview for just 10 min. Brief introduction and standard HR questions were asked like:
What are your future goals?
Are you willing to join this company?
Any plans for higher studies?
Ask one or two questions in the end.
Preparation Strategy:
First be clear on which path you are taking - Hardware, Core, Software, Analyst or anything. Once you have decided half of your work is done.
Start from the basics. For Hardware, start from digital electronics and analog electronics. Atleast 2-3 months of time is required for good preparation. Starting as early as possible will always be beneficial.
Along with hardware, prepare for basic coding questions because many hardware companies have few coding questions involved in their interviews and OTs.
Keep atleast 1 good project which you have done and can confidently explain.
Keep practicing aptitude and reasoning questions also.
Prepare a notes for everything you have read. It will be easy at the end during the interviews.

Additional info for our viewers:
Work hard, you will be deserved with the best.
I did an internship in a core company and later realised that I was interested in hardware and changed my field. It is okay to not have an internship because you get much more time to prepare and excel.
If you haven't started till now then start it today. Little preparation everyday helps at last. Divide and plan your study so you cover all the topics.
Don't get sad if you miss a chance, something better will always be waiting if you have worked hard. Learn from your mistakes and correct them.
Take help from seniors and friends in the same domain.
All the best.
