They sent me a take home assignment: "Your task is to write a python function which accepts a dictionary as input and returns a dictionary as output. The output dictionary should be a modified version of the input dictionary. For every key-value pair in the input, then, if the value is not a dictionary, you should replace the value (`old_value`) with `{'_content': old_value, '_type': str(type(old_value))}`. If the value is a dictionary, then you perform the same substitution on that value, etc. The function should optionally also accept a parameter specifiying to which depth this substitution should proceed (how many iterations into the sub-dictionaries etc.). Please write the python function in a single standalone script `substitute.py`. Your answer should run in any `python3` environment, and should not require any package imports. The script should accept 3 command line parameters - the file-name of a JSON file which is loaded and passed to the first parameter of the function, and an integer which is passed to the second parameter of the function, specifying the depth of the substitution, and finally the path of the output file. The script should save the output of the function to the output file. For submissing what you have done: Please create a private project on Github with the following naming: `SuperDuperDB_coding_task_python_YOURNAME` and invite <employees> once you are done. Also please ping us here. Thank you!" After I completed that they sent me a questionnaire asking for links such as github and linkedin, salary expectations, and a list of what technologies I've used. I got rejected here, although there was no reason for them to ask this AFTER I did the take home assignment.
