Tech startup internship for M&A career?

Hi, I'm Korean and currently a junior at one of Korean IVY with a decent GPA(3.78) and have internship experience in major local IBD(2months) and MBB (2months).
My career goal is to work in BB(M&A), but struggling to get an internship in BB and global PE.

I once met one banker who graduated from top US MBA school and recommended me tech startup internship, telling me that in the US, lots of candidates for BB have consulting, tech startup, banking experience in their resume.

After hearing that, I found a 2-month internship in the business development team at an AI-based tech startup that is growing at a fast rate and receiving $70M investment in total.

I think this opportunity would give me a competitive edge since I can have real industry experience and puts some buzzwords like AI, deep learning in my resume.
But worry that this could be viewed for interviewers that I don't have enough passion for banking.

What's your guy's opinion? Do you think this will help my career for M&A?

Thanks for your reply in advance.
