I had two interviews for a position as a technical writer. The first interview was with the technical writing manager and another writer, and the second was with two HR people.
The first interview went very well. Both interviewers asked good questions, answered my questions well, and generally seemed like good people to work with. They then gave me a fairly standard technical writing test in which I had to improve content written by an engineer. The test was a good approximation of real technical writing work, and I performed well on it.
In the second interview, HR people basically asked questions about myself. I have never understood the point of this type of HR interview. A behavioral interview would be fine. But why should HR ask me questions that the hiring manager has already asked? To me, this sort of HR interview presents an immediate red flag that the company has too much bureaucracy, as the company does not trust business units to do their own hiring.
The actual HR interview was pretty standard: "tell me about yourself", "why are you interested in this job", "can you work on multiple things at once", etc. Most of the interview went well. However, at the end, two things disillusioned me. First, I asked what sort of career development opportunities they have, and one of the HR guys said "well, you know we are not a huge company with tons of management layers." To me, that answer reflected a very narrow view of career development. Career development can include working on new projects, covering for temporary leave, training, etc. But he did not say any of that.
Then the other HR person asked me about salary requirements. I told her my current salary, and she told me there was no way PTC would pay close to that. I asked her what that meant--10%? 20%? At least a range? She refused to give any sort of number, and said I had to come back with a lower number, and they would see if my number fell within their range. To me, that requirement was unprofessional and unfair. I had already given them a number; they should give me a number and see if there is any way for us to meet in the middle.
Overall, my interview experience gave me the distinct impression that the actual work would be good, but that the other issues, including salary, work flexibility, bureaucracy, and room for development would not be so good.
