Having read through the reviews on Glassdoor, I wasn't expecting a smooth process either. However, since I am a local candidate, I didn't have to go through the hassle of travel/stay reimbursements etc. The reviews were true to the core: the recruitment process is a clear indication of the complete chaos in the company.

I was invited for an onsite after clearing the initial phone screen, which was a fairly simple algorithmic challenge. Just revisit your algorithms and data structures, especially search, sort, lists, trees, graphs, and string manipulations. An advice to candidates is to not overdo the preparation, as they come with a mindset expecting 'the' answer they were looking for. Even if you outsmart them with an efficient solution, it's still frowned upon (which is rather untrue for most companies in Silicon Valley).

The onsite interviews were pathetic, with some interviewers jumping straight onto whiteboard coding without even a formal introduction. The questions ranged from generating random numbers between 1 and N given a function that returns 0 or 1 with equal probability (binary to decimal!), ways to provide contradicting assignment statements from a list of string assignments of the form ['a=b', 'c=d', 'd=b'] ['a!=d'] etc., string anagram matching, and binary search trees.

The engineers seemed technically sound and professional and will indeed provide you enough hints in case you run into troubled waters.

A question involving the indirect application of DFS on a graph, to prove if a list of assignment statements contradicts.
