Exilon Industries Interview Questions and Answers

Interview preparation tips for other job seekers - It is a very bad company.....no job security,. politics is everywhere in this company.

Round: Resume Shortlist
Experience: CGPA cut-off: 7.5

Round: Group Discussion
Experience: GD of about 5-7 min.

Round: Technical Interview
Experience: Comparatively shorter than HR interview.
Technical round will include Business analysis, case studies. They will look for your approach, clarity in thoughts and considerations of all the possibilities

Round: HR Interview
Experience: HR interview will go for almost an hour.
 HR round will have all standard stuff like your future plans, internship details, your strengths and weaknesses
 One of the previous interviews had a case study on "How would you increase sale of Bank's insurance plan?‟

General Tips: 1. Be thorough with your resume
2. Go through the material available on the ftp server, have a look at case studies and puzzles.
3. Start preparation early.

Round: Resume Shortlist
Experience: On my own, with feedback from friends. Kept it simple, so that even a layman could understand what I've done in the various projects that I was involved in. It pays to be truthful, and yet, at the same time, to advertise one's achievements. In most of the interviews a random point on my resume was picked out and I was asked about it.

Round: Group Discussion
Experience: I did prepare in a group for the one day of case study prep that I did (and my other group member managed to get into BCG), so I guess it probably helps more than preparing alone.

Round: Puzzle Interview
Experience: Typical puzzles come coupled with recurrences which can in turn be coded into algorithms. See if you can get your hands on any of these.

Round: HR Interview
Experience: Interviews were puzzles based, plus algorithm/coding based. The puzzles weren't easy, but were doable with sufficient time. Two of my interviewers were happy to provide me with hints along the way and I kept telling them what I was thinking, no matter how naive it might be - for example, I'd give an exponential algorithm for a greedy/dynamic programming problem [if that's Greek and Latin to you you probably don't have a shot at Google!] and then tell them that it was a bad algorithm, and that I was trying for something better next. Typical minchange-optimal division type recurrence based algorithms were common, coupled with coding of the same algorithms [brushing up on coding skills helps!]. I was also asked questions on Operating Systems [some synchronization / TeX type questions], Cryptography and some puzzles based on simple intuition and mathematics.

Round: Other Interview
Experience: No Preparation. CSE BTech curriculum + common sense more than covers what one can be asked in the interview. It probably helps to be fresh with C++ syntax, however. Written test + 4 interviews (45 minutes each). 10 shortlisted at the end of the written test, 5 shortlisted at the end of the first two interviews, 4 (2 BTech, 2 MTech) made final offers.
Tips: Ideally, any BTech/DD from CSE should be well prepared without doing much, except probably practising coding. Algorithms: Greedy and Dynamic Programming crucial. Learn how to solve recurrences, if you don't know already. Don't know how important graph algos are, but searching, sorting are pretty important too. Brush up on these if you don't remember. Operating Systems: Synchronization

Skill Tips: Keep it cool with Google. Even a t-shirt is fine (they told me that - even though I was wearing a tie). Consulting interviews require the usual Shirt - Jacket - Tie combo. It helps to wear a jacket to hide the crumpled shirt inside. Smile!
College Name: IIT BOMBAY

Round: Test
Experience: You’ll find it easy if you are already preparing for CAT. It isn’t too tough and they test only core Indutrial Engineering knowledge.
Tips: 1. Prepare well for the test.
2. Take exam in groups.
3. Prepare for CAT and GRE.
4. Solve TIME test papers for speed.

Round: Interview
Tips: 1. Be confident.
2. Be clear about whatever you speak to them.
3. Memorise some real world example related to each topic. For example the use of the revolutionary algorithm and assembly line problems.

Skill Tips: There will be a section on mechanical engineering. IM students need to study for that. It’s better to have some managerial skills. Also be ready to write that you will work for a period of 10-15 years in TATA motors.
