First thing you need to do is a old school test in HackerRank platform, where you have 21 questions to answer and 4 code challenges to develop, all of them in 90 minutes. Most of the questions are quite extensive for such amount of time, so at least 50% of the time is to read the questions, which means you have around 45 minutes to find out the answer of the 21 questions and develop 4 codes. The questions are from very easy to quite difficult, but some of them are wrong, once you put the same code in the compile it just give you an answer that is not an option. For the codes challenge are quite hard due the time remaining, at the end I had only 5 minutes to find a solution and code each of them. The HackerRank platform is bugged, for the questions you know how much time you still have, but not for the code part, making that really challenge to manager. If the test was 90 minutes for the questions and another 90 minutes for the code, that would be an average level of difficulty.

It's not allowed to share the questions, but you can expect deep knowledge of memory allocation and auto casting type definition, most of the questions are about these subjects. An example of easy question would be: geek = make_tuple('a', 10, 15.5); auto a = get<0>(geek) auto b = get<1>(geek); auto c = get<2>(geek) which kind of type is a, b, c? Or maybe they could ask, what is the result of a+b+c

The full interview process is really outstanding. Each of the four process steps are very exciting and you get to realize that top coders work for such an amazing Company!
Anyway there are four steps regarding the interview process : 1)Hackerrank online test (very nice); 2)HR call; 3)Code pair live interview on Hackerrank; 4)Final onsite interviews

The interview process is long, tedious and hard.
It starts with a HackerRank test of about 12 questions of which more then half are programming assignments where you are expected to handle input and corner cases, others are just pick an answer questions. The time limit is about 2h and most people fail at this stage, it is unlikely that any candidate gets all 12 questions done in amount of time.
After HackerRank testI had a pair programming interview on HackerRank with on of Senior Engineers working there, the session takes about 1h where my engineer was taking more time to put the questions then me to answer them, this one felt easy.
In both cases questions are very narrow in scope, in the sense that there are particular traits/abilities to have related to C++ language that are needed otherwise one would easily fail the interview. Most questions are about template meta-programming and C++ templates, algorithms, design patterns, concurrency, etc. are kind of left out.
After this you get invited to a discussion with people from management for further screening.
