I've heard that it's really hard to get into big-tech companies. That, since they pay top salaries, they can be very selective in who they hire. I'll plainly admit that it's not my experience, and offer a different narrative.
And while I admit I believe I understand more or less why it occurs, I still find it counter-intuitive that it was easier for me to find software engineer job at Amazon and Google[1], than to join smaller French companies.
Note
[1] I also heard good feedback from Meta recruiter, up to a sudden email stating that there were no more job in my location. Followed two days later by announcement of mass layoffs.
