As the title suggests, I did a 20-minute phone interview for a remote software developer position. One of the questions was "have you used any frameworks with X language, specifically Y framework?" My answer was "no I haven't used Y framework, but I have experience with Z framework."
The rest of the interview went fine and he explained that the next interview would be related to theory, followed by a short coding test with Y framework if I passed the theory interview. Maybe I should have brought up the fact that I don't have experience with Y framework again, but I didn't think about it until after the interview. The job posting had wording similar to:
We use Y framework, but are always on the lookout for the best technology for the job.
I took this as it being possible they just want a good developer, not someone necessarily experienced in that framework. However, if that's the case I don't know why they would give me a coding challenge that uses it. Obviously, I most likely won't do well. Is this a red flag?
Also, he set me up for the interview next week. I could study up on Y framework, but I think it might be a waste of time. If I don't get the job, I won't use it and if they want someone experienced in that framework I won't be able to learn it thoroughly enough before the interview.
