Infosys Interview Experience for System Engineer

Hello geeks,  I am from ECE Branch and I have applied for a “System Engineer Role” in Infosys. One of the most reputed IT Firms in India. There were a total of 2 rounds Conducted. In the first round, an exam had questions on Mathematical ability, logical reasoning, verbal reasoning, pseudo code, and puzzle solving. Questions were divided as:

• 10 questions were from mathematical ability,
• 15 questions from logical reasoning, 
• 20 questions on verbal reasoning, 
• 10 Pseudo code,
• 4 Puzzle solving

The questions in this round were all easy-medium range toughness and the pseudo-code was of basic level. The puzzle-solving was easy but interesting. The result was released after 1 week.

“I thought that the interview would be related to the languages I mentioned in my resume (Core Java, Python) but it turned out to be the complete opposite. I was asked questions completely related to my core subjects. The interviewer was also from my branch he said.

The interview questions that were asked during my interview are as follows:

• Tell me about yourself?
• What is your favourite programming language and why?
• What subject do you like the most in your academics (Core Branch)?
• What is the difference between full-wave vs half-wave vs bridge-rectifier?
• What is negative voltage?
• How do you measure resistance, current, voltage?
• What is meant by peak voltage?
• What is the use of oscilloscope?
• Applications of the subject on which the question were asked (Digital Signal Processing)
• What does gaussian filter do?
• What are affects of noise on system?

I have answered all the questions as I was good at the subject. The interviewer just said: Thank you for the interview and you will receive an email if you get shortlisted. I have received the result in 2 weeks and got selected for system engineer role. So geeks do remember to not only prepare for the languages you mentioned in your resume which might be C/C++/Java/Python but also make sure that you also choose a subject of your core curriculum and prepare topics related to that. Happy Learning and Thanks for the read!
