Interview happened during mid 2015. First round was a telephone screening, then online coding round and then 2 rounds of f2f technical interviews. Telephonic consisted of few puzzles. Coding round questions were easy, but had space & time constraints. In f2f, few ds & algo questions + programming puzzles + a design question. They expect you to write proper code using pen & paper, which is expected in most of the software engg interviews.

Applied online, got a call from Neustar parent company a 2-3 days later who explained what the company does and what's the expected pay for the position (really low, way below industry average). Still took a chance and interviewed because the hiring manager was very nice and kind. We had a great chat and he sent me a link for a online coding challenge. Finished the challenge and had another technical interview with an engineer. The engineer was very impatient from the beginning and had a temper for what he considers "slow" coding. Not helpful whatsoever and the sentence that came out of him most was "make it work." And when the code did work he actually sounded surprised and repeated to himself, "Oh! It works." Overall a very horrible interviewing experience. Absolutely unprofessional and very rude to the interviewee. The quality of a company really reflects on the quality of its engineers and I feel like I already have a great sense of what this company is like.
