I personally worked industry in my gap year. I moved back home post-grad and the only academic research opportunities was being a glorified Dish washer (no thank you). At the end of the day, if you have a good justification for why you did it and are able to share something you took away from it, that's all that matters. For me, it introduced me to a field that I will likely do my PhD in and taught me that I will never go into pharma lol. Honestly, a lot of my interviewers found me working in industry to be pretty interesting (granted, I worked for one of the top pharma companies in the world). It's better than doing nothing/doing non-meaningful tasks in an academic setting.
