Step 1:
Codility test (2 question, 70 minutes)
Language requirements: preferred java, c++ or python
Complexity requirements: none
I think this test is something to evaluate coding style and approach (ieg use built in libs vs rewrite everything by your own).
1.1- Find common minimum
Given 2 arrays, find the minimum common element.
1.2- Stack calculator
Given a string input, each char can be [0-9] or [+*].
The test is easy if you stay focused on doing things in a simple way, it tooks 40 mins.
Step 2:
Phone interview. [update needed]
