The Cad World Technical Engineer Interview Questions and Answers

Round: Resume Shortlist
Experience: I had a standard resume for this company as per our institute placement cell norms.
I had put in a lot of emphasis on my extra-curricular activities while preparing my resume since my CGPA was less. While applying for the core companies I also mentioned about the projects that I had completed in the past few years. The main difference in my resume for different companies was related to the “Areas of Interest” and the subjects studied.

Round: Test
Experience: Even when I was preparing for CAT I always knew that my preparation for this exam would always help me with the aptitude tests that companies conduct as part of their recruitment process. And it was the case with most of the aptitude tests I gave during the placement season.
The written test consisted of some tricky mathematical puzzles. One of them that I remember was to find the minimum number of people required to detect the bottle containing the poison out of the 1000 given bottles. The test comprised of 50 such mathematical questions/puzzles and the time allotted was only 30 minutes. They also had aptitude based questions. Around 180 to 200 students appeared for the first round. The company short-listed only 24 candidates for the next round.
Tips: Preparation of puzzles for this company would be helpful.

Round: HR Interview
Experience: The second round was the interview round. The interview was divided into 2 parts. The first part was a mathematics quiz and the second was an aptitude quiz. They gave us the question set and asked us to solve them. There was no specific time allotted. We had to solve those questions and give it back to them. The questions were easy aptitude based questions. If there were some questions that we could not solve we were asked to state the approach that we adopted to solve those questions. After reviewing the paper, they started asking me some mathematical puzzles. There was one other question, I don’t remember the data exactly but it was related to a man and his movements along a downward going escalator. The man started moving up the escalator with a certain speed relative to the ground and then while coming down his speed increased by a certain given factor, I was asked to state the absolute speed of the man.
Then the interviewers moved on to the HR questions. They inquired about my internships that I did in my past years and asked me to share the experience that I had in each of them. I had done 2 internships which I told them about. They next asked me draw comparison between the two and state which I felt was the better of the two and why.
The company finally recruited 12 students.

General Tips: I would advise students to have a brief overview of few commonly asked puzzles in interviews. Preparation for aptitude tests before hand would be very helpful.
College Name: IIT ROORKEE
Motivation: I acquired the knowledge about the profile during the pre-placement talk. Also since the company had come last year as well and recruited one of my seniors from my department, I garnered some knowledge about the profile and the company from him.
