This is still WIP, but I'd appreciate you taking an early look :pray: Outstanding issues:

• No mapping for educational achievements
  • Greenhouse requires educational achievements to be specified as IDs from a fixed list, instead of just free-form text. https://developers.greenhouse.io/harvest.html#post-add-candidate https://developers.greenhouse.io/harvest.html#post-add-education
    • Solution A:
    • Add a schoolId, degreeId and fieldId to the profiles, add a new profile for listing these.
    • Solution B:
    • Request the list from the API, check if there's an exact text match, extract ID, use that; otherwise, error out and return the lists
    • Solution C: Ignore for now (like e.g. Merge.dev does)
  • No mapping for Answers
  • Greenhouse has "custom fields", is that the same concept?
  • Other providers' maps don't use the mimeType field yet, instead matching on file extensions

Greenhouse requires educational achievements to be specified as IDs from a fixed list, instead of just free-form text

That is a complex solution. I am curious what are the benefits for the recruiter using Greenhouse. The list of schools can never be complete.

I would go with Solution C -> Ignore it for now. Once we will have requirement to support it from our customer we can find solution. But it will bring a lot of complexity, that will need to be solved on the client side.

No mapping for Answers

I do not see support for questions/answers in Greenhouse API nor the web.

If I recall correctly from the time we implemented their job board API, they allowed defining custom fields for candidate forms.

I will check if the mime type is an alternative for file name in case of Workable and Breezy HR maps.

@tmladek the PR is hard to read as it contains changes from #346. I propose to change the base to #346 or merge #346 to main, I have already approved it.
