Take home test expected to be completed in 3 days - build an application to filter coordinates from given list (as a file with JSON lines) in a specified radius.

Poor answers will be in the form of one big function. It’s impossible to test anything smaller than the entire operation of the program, including reading from the input file. Errors are caught and ignored.

Good answers are well composed. Calculating distances and reading from a file are separate concerns. Classes or functions have clearly defined responsibilities. Test cases cover likely problems with input data.

One month after test submission got a 1-hour call from HR telling that the delay in communication was related to accident where my email was lost, providing good feedback on my test submission, describing all the departments in the company and asking for my preference between the departments (core/API/integration/frontend).

Several days later was declined by email.
