Started with Codility test, 2 simple question, after that an interview with team lead and after that interview with group lead. Both interview was 2 hours long technical interviews in C. They were very nice.

Codility- You get a CSV formated string, remove all rows that have NULL int them.

First question team lead - implement atoi in C. Edge cases!

Second question team lead - you have 2 function, 'add(func, time)', 'run()', implement something (like a struct) that will support adding functions and there time of run, when run function is called, al the functions need to run at there time. Example: add(func1,2) add(func2, 5) add(func3,3) add(func4, 6) run()

So the the first function will run after 2 seconds since the run called, then func3 will run after 3 second since the run have been called and so on..

Third question team lead- desighn a data structure that supports get, set, setAll in O(1).

Second question group lead- you have 1Mb of memory, implement the functions malloc and free in C (of course not using the stdlib functions). How much memory your implementing requires? and how much of the 1Mb is actually left for the user? Remember malloc need to return an Pointer to an address and free gets a pointer and frees it.
