Very Easy Interview
I applied through a recruiter and the process took 1+ week - interviewed at MongoDB in September 2013.
Interview Details – I took part with 2 phone interviews. 1st interview was just to introduce myself and the recruiter. A quick tour on my career, interests, aicnd what MongoDB is looking for. It was not challenging at all.
2nd interview was supposed to be a technical interview and it was. Since I come from Java world the most of the questions were Java related. All of them were very easy for me to answer and I did not find this interview challenging whatsoever.
The problem here is that they were not interested in continuation, which is quite difficult to understand for me. It seems that this was pure waste of time, maybe they just make their statistics on number of interviewed persons. This just does not make sense to me. Overall experience with this company is very poor because even I asked for some feedback they just ignored me.
I applied in-person and the process took 3+ weeks - interviewed at MongoDB in December 2010.
Interview Details – As a member of the open source community working with frameworks based on the product I already had a lot of experience and interaction with many people in the company. This lead to an interview and discussions about jobs before that. The interview involved multiple meetings with engineering folk and managers which resulted in a job offer. We then went and back with multiple responses before the offer was accepted. The whole process seem labored and unprofessional (informal) in many ways.

I applied in-person and the process took 1 week - interviewed at MongoDB in November 2011.
Interview Details – Interviews were scheduled over one day. Process was really enjoyable. I was asked a couple of interesting coding questions to see how I think but the majority of the interview time focused on my experiences as CTO, why I was interested in working at 10gen, and what I wanted to do at the company.

Interview Details – As I started out as a contractor, I didn't really have a formal interview. My "contractor interview" consisted of talking with my manager, the CTO and president for about 15-30 minutes each. I think it was more to see whether I would fit in culturally as I had already show that I was able to do my job.
Negotiation Details – I just mentioned an amount I was going to be happy with, with a little bit more. That got accepted.
I applied online - interviewed at MongoDB in December 2012.
Interview Details – The single biggest pain point was how long this took. And, every time I got a call from HR, it was to tell me that another call with someone else had been scheduled.
In total I fielded over 12 different onsite and offsite meetings over 3 months. There were several times when I was convinced that this is a serious waste of time.
After the technical phone screen, I went in for an in-person invterview that lasted 4 hours and there I met 4 people. That same day I received a call from one more person.
It took 3 months to receive an offer.
Interview Question – We have a person who logs into a website using their Facebook credentials. Anything they post to that website can be seen by their friends and those friends' friends only.

Interview Details – Applied online and got a call from the recruiter. Had an initial phone screen. I answered all the questions except the C++ ones. I didn't know they were big on C++ knowledge.
Interview Question – The questions on C++ were the unexpected ones. Interviewer asked me to write a very simple coding questions, but asked me to use vectors from the C++ standard library and use iterators for iterating through those elements. I couldn't answer as C++ isn't on my resume. Answer Question
