Entrevista
Applied online (LinkedIn ad), was sent an assessment. Spent two days on the assessment design, testing and deployment with complete CI/CD pipeline to Elastic Beanstalk on AWS. Was given 5 working days before I could submit the application. However, I got a rejection even before I submitted my code. I submitted my code nevertheless and after 3 weeks got a shoddy feedback which said that testing was 'lacking', code was not clean enough or subpar and naming of endpoints did not adhere to industry standards besides lacking containerisation. Last three are all non-functional requirements which they specifically asked not to bother about and thorough testing was added.
Would advise not to waste your time on Wex as all they are doing is pretending to be brilliant.

As a manager, I had to take the coding test and failed it.
Important thing about their coding test — it is extremely unprofessional.
1/ They tell you that the test is timed. That is a lie. Every question is timed, from 15 seconds to 10 minutes.
Yes. 15 seconds to answer some multiple choice question.
2/ For ALL questions, the time is inadequately insufficient. 10 minutes to write a function with dynamic programming, sorting and matching.
3/ They lower your scores on purpose. For example, they gave me 30% score on Python (right?) when I answered at least 80% of the questions,
4/ The entire coding test was completely irrelevant to the Management title and to the subject domain (AI)
5/ College-level questions, such as "what is the default value of the parameter X in function Y in the package Z. Don't use Google". Right?
All in all, completely unprofessional setting, feels like a card game with a cheat. Stay away from them… they probably do the same if they hire you...
