I applied through a staffing agency. I interviewed at Thoughtworks (London, England)
Interview
That was the very first stage - home work.
I was given a "home work", which consisted of three problems, where I had to select one of them and do it offline at home. The time limit was 3-4 days.
The company suggested that any of these problems is worth of 3-4 hours of coding.
I received no feedback on the submitted solution.
Interview questions [1]
Question 1
The problems were boiling down to the following:
1) Graph path finding algorithms, (the shortest path, number of paths etc.)
2) The optimal scheduling problem
3) An obscure language interpreter (which boils down to the non-LR grammar/parser)
All the above problems were coming with some twist and also the condition was not use any external libraries apart from testing frameworks.
I applied through other source. I interviewed at Thoughtworks (Singapore) in Feb 2026
