I applied online, and the process took two weeks.

This review is for the London office. I applied through LinkedIn and had an initial chat with a recruiter, followed by a first-stage technical chat with a nice, decent chap. The next stage was a technical test to do. The recruiter on the phone told me it would take roughly four hours. I have completed the task to what I think is an acceptable, satisfying degree for a test exercise, especially since the test PDF says they need to see your "engineering skills" on solving problems. The task deliberately has missing information (it is mentioned in almost every review) on how to do interest calculation, but when you find out how, you will be surprised it doesn't match the test cases (some minor discrepancies in the second decimal place). On top of that, their examples show rounded values, so you don't really know what is going wrong with your calculation.

The feedback from the team was shocking! They basically assess your task as if it is going to be merged into their master branch. They look for test coverage for rate calculation, which they have no clear requirement for in their PDF. They look for a README file to say "open the app and press F5". The bottom line is they are not clear on the purpose of their technical task and didn't state it clearly, which makes candidates feel their feedback is unfair! I wish I hadn't wasted any minute on this interview process! They don't really consider that you have a job and a life, and you will be doing this in your spare time (with other tasks from other companies if you are actively looking)!

The task was to build a loan quotation app.
