Had a call with the hiring manager then immediately with an engineer to go over technical experiences. Soon after, was given a take home challenge and put into a slack chat with another engineer. This is where there was some issues and red flags. The engineer was extremely vague in answering the questions and gave "maybe" responses. I was not able to get a single straight answer to my questions about the requirements. The other main issue was that the coding challenge sent was outdated (libraries/tools are many years old; yet the engineer said it was fine to upgrade/update) and there were no clear instructions what you can't do. Even the engineer wasn't clear on what you can't do. We scheduled an on-site and last minute, they pulled the plug with no real details or specifics. Massive waste of time. If this is how they treat candidates and based on the kind of engineers I was put in contact with, then I don't want to work here.
