As a soon to be Computer Science and AI graduate in London where should I apply?

I am about to finish uni and looking to get a job in London as soon as I finish. I have had two software engineering related internships and have built countless apps and products.

I am really passionate about building products and not so much doing “nitty gritty” programming for a very small feature of a very large project.

I have studied computer science and AI and looking like I will graduate with a 1st class degree.

Unfortunately I have no idea of what company I should be looking at joining. I am planning on applying for graduate jobs at Facebook and Google in their product related departments. I am not really bothered about money as I have the rest of my life for that. I just want great experience and to be around people who are way more creative and talented than me.

Where else should I look at applying?
