The interview process consisted of two rounds of phone interviews.
The first was a two part interview and the first was a coding interview using coderpad over the phone and the second was a Skype interview with two managers and an hr person.
The second round was a phone interview with two more managers and another hr person. This round was non technical, but I was asked about my previous projects and what technologies I've had experience with.
The entire interview was organized through and interview 'coordinator,' which made it a bit difficult send a decent thank you letter.
I know I aced the technical portion...
I believe I didn't receive an offer because I am not a pure CS student, and I don't have experience with higher level concepts like database use or web design. Beyond this, I believe I didn't convey thorough interest in the position--of course it's hard to be excited about a position at a company with the reviews that Cambia has.
I felt I've grown a bit from the interview, but the whole process was a bit clunky, time consuming, and I feel, slightly rude. Cambia never sent me a rejection letter and simply stopped responding. To be fair though, they never said they would; simply that they would be sending out offers within a week.
A bit of advice if you are applying here. For the coding portion use Python if you know it! It will greatly simplify the coding test.
