HR said that there are other positions suitable for me, and there is also a lot of room for promotion. Can you do it? HR, this is ...

There is a great possibility that the position you are applying for is either suitable or not urgent, while the other positions mentioned by HR are urgent and difficult to recruit. I guess the other positions HR told you were marketing positions, right? Now many HR are selling dog meat, attracting people to interview with a position, and then trying to get you to apply for a more difficult position. In fact, this is nothing, mainly depends on whether you are interested in this position, the scale, prospects and personnel of this enterprise. I don't know how you replied to HR at that time.

You insist on applying for the marketing post, no problem. At least give HR an impression that you know your career direction very well. HR will seriously consider you unless the marketing post is full.
