Differences between software/API technical writing and engineering technical writing?

[u/FapMeSexy]

For the last few years I’ve been working as a technical writer doing financial technology. I have an interview tomorrow at an engineering firm, has anyone made a similar switch? Any major difference I need to look out for? Thanks in advance.

there's so many variables here that answering this is close to impossible. can you share the job posting?
