Very Easy Interview

Software Engineer Interview

Software Engineer
Greenville, TX

I interviewed at L-3 Communications in September 2012.

Interview Details – I gave them my resume at a University job fair.
I got the call the next week and the interview was the week after that.

The interview day was with about 20 other new graduates and was very casual.
I interviewed with 3 different people. Each was about 30 minutes.
The questions were easy. Nothing really technical. The people were very nice and I really enjoyed the day of interviews and tours.

The company and I are not really a good fit, so I was not surprised or disappointed when I did not get an offer.

Interview Question – What do you want to do?
Give an example of a challenging problem and how you handled it?
Strengths and weaknesses?

Difficult Interview

Intern Interview

Intern
Greenville, TX

I applied through college or university and the process took 1 week - interviewed at L-3 Communications in October 2012.

Interview Details – I met a recruiter at a college career fair and she told me to apply online. I listed her as a reference and then I was invited by phone to fly out to Greenville, TX (at no cost to me of course) for an interview. I left Thursday morning and came back Friday evening. The hotel was really nice. More representatives took us out to eat Thursday night at a nice steak restaurant. All day Friday was the interview. We watched two presentations and did two interviews before lunch. We sat at individual tables with our names marked so that the interviewers knew where to go. The interviews were managers who actually did this job or have done this job for a living. The questions were conversation style and quite thorough. They went over my resume word for word and really dug deep for my knowledge of each item listed.

After those two interviews we toured the facility and let me just say it is amazing. If I was on the fence about wanting to work there before, the tour solidified my desire to really want to be there and learn what they had to teach. Futuristic is not the word. It soon became apparent that these people can teach you everything you need to be successful in any part of IT. Even if you use this as a stepping stone, any company would be lucky to have you after L-3 is done with you. When we came back there was the third interview and we got back in the limo and headed for the airport to go home.

Software Engineer Interview

Software Engineer
Bristol, PA

I applied through a staffing agency and the process took 3 days - interviewed at L-3 Communications in December 2011.

Interview Details – Quickest Interview process I've had yet. 4 days from phone call of the recruiter to me accepting the offer!

1) Recruiter calls me, and I express interest (letting him know I already expect an offer from a different company at XXXXX dollars per year).
2) I have a phone call with the Director of Software.
3) I have in-person 1-on-1 interviews with 5 members of the software team.
4) I receive an email offer letter from HR for more money than XXXXX.

Very smooth process.

Interview Question – The interview was more conversational and it was with multiple team members.   View Answer

Negotiation Details – I had another offer and told L-3 what it was. L-3 beat it, and I accepted. Unfortunately, the first company was willing to go much higher after I told them I was going to decline in favor of L-3, but I'm glad I took the position with L-3. I would always recommend negotiating, but I was not willing to pass up the great opportunity!

Systems Administrator Interview

Systems Administrator
Salt Lake City, UT

I applied online and the process took 2 days - interviewed at L-3 Communications in June 2012.

Interview Details – They were very organized and communicated clearly the timeline, what to expect, where to show up. I would suggest that you research the company in advance and be prepared to show that you are willing to take responsibility for your learning and to ready to hit the ground running in your new environment. Also it helps to be relaxed and project confidence.

Interview Question – What is the best compliment someone has ever paid you, and why did you select it?   Answer Question

Reason for Declining – I was wanting to take my career in a different direction.

Research Engineer Interview

Anonymous Interview Candidate
Wilmington, MA

I applied online and the process took a day - interviewed at L-3 Communications in March 2012.

Interview Details – I applied initially for an optical engineering position, but the recruiter asked me to instead apply for a research engineering position. I had two phone interviews; the first was with the CTO, and the other with the person who would be my direct boss. I was then flown to the company for the interview. The process was quick; I flew in Sunday at noon and flew out Monday at 2:30. I interviewed from 8:30 to noon with 5 different people. One gripe I would have is that it felt like none of the interviewers other than the CTO and direct boss again had much to talk to me about. The interviews went well, and were fairly easy.
At the end, I was told by the direct supervisor that he was very pleased and I should expect to get one more phone interview within a week from the HR rep, at the very least. It is now over a month later, and I have heard nothing from them.

I applied through an employee referral and the process took a day - interviewed at L-3 Communications in June 2011.

Interview Details – Referred by a friend who was aware of my particular skill set as a Electronic Maintenance Technician in the US Army. I was called for a brief telephone interview and then asked to visit for a 1:1 interview. I dressed in a suit even though they are very casual which made a good impression. I toured the facilities and asked many questions to how they saw my role.

Network Engineer Interview

Network Engineer
Salt Lake City, UT

The process took a day - interviewed at L-3 Communications in March 2012.

Interview Details – I met them at the career fair and things looked really positive. But then I didn't hear back from them for few months and finally got a call for a phone interview. They asked me quite a few networking questions but I told them I was not a network guy, more a modeling/sim guy. They asked me a question about pointing lasers at one another since that was my research area for my PhD. The question was if I had two aircrafts traveling at the same altitudes, how would you figure out the direction a laser should point in Airplane 1 to hit Airplane 2. I didn't think it went well but then they wanted to me in person. I visited two groups there: Network and RF group. I gave my presentation to the network group about my project, it went really well and they were interested. One guy wanted to ask me about FPGAs but I told him I didn't have experience in that and he was fine. He then asked me about different network protocols (TCP/IP and UDP) and when certain ones can be used.

After that another interviewer came in and asked me about the OSI model and which one I thought I would fit in the best. He asked me a question about pointing cameras to one another on two trucks placed at different locations in space. He then also asked about the difference between C/C++ and C#.

I met with the RF group and got a tour of their facilities. Not too many questions asked there, just what I wanted to do with my career.

We then went out to lunch and had a very pleasant discussion. I was sure I had the job but they were looking for someone with more of a networking background. Still I expect to hear back from their RF group as they are also interviewing candidates.
