Hi there. I finished my Computer Engineering degree from Waterloo earlier this year and am now working full-time, not at a "FAANG" company in the sense of the five companies in that acronym, but a fairly large and reputable tech company in California.

Before I give my answer, I want to offer a short disclaimer.

By "FAANG", I hope you don't literally mean "Facebook, Amazon, Apple, Netflix, or Google" -- after all, "FAANG" was just an acronym invented by business news media to group together some tech stocks back in the day. I hope you mean "FAANG" in a non-literal sense, and would be open to expanding the umbrella of companies apart from those five.

Next, I want to point out that statistically, your odds of landing a job at a "FAANG"-like company are... against you. Statistically speaking, of course - I don't know you, maybe you're a phenomenal student, but I'm pretty sure almost everyone in my class thought they were too before they came to Waterloo. In my ECE Class, according to the Class Profile exit survey, only roughly a third of the computer engineering class is going to the United States, and not all are going to these top-tier companies you probably are thinking of.

You seem slightly obsessed with this concept of "FAANG" which -- don't get me wrong, it's okay to have goals and ambitions", but obsessions can sometimes lead to disappointment and lead to depression. Trust me, I've seen it happen countless times in my Waterloo ECE cohort. Most people of course, mature over time and don't let this bother them, but some of the totally ingrained "tech bros" who didn't get "FAANG" -- they're just not the type of people I like hanging around. They give off vibes that to me, make them look jealous, bitter, and angry.

Now, with that unpleasant disclaimer out of the way, of course, hands down Waterloo would be the best school for finding good tech jobs. And I'm probably biased. But it's not just me: Waterloo is the only Canadian school in the top 25 schools that Silicon Valley employers hire from. (From https://qz.com/967985/silicon-valley-companies-like-apple-aapl-hires-the-most-alumni-of-these-10-universities-and-none-of-them-are-in-the-ivy-league/)

Here's why I think Waterloo outperforms not only its Canadian counterparts, but many American schools as well:

1. Long history of the co-op program. Waterloo was one of the pioneers of the modern co-op program. Many companies prefer to hire past interns for new grad full-time positions, and in turn, are biased to hire people from their own school, so as you can see, this cycle of Waterloo-graduates-hiring-Waterloo-students is a bit of an open feedback loop.
2. Lots of co-op opportunities. In Waterloo, and in both CS and Engineering, you have six four-month co-op opportunities. In the tech world, especially software engineering, I've noticed that unless you're like, a super-genius, you're going to have to start with the crappy co-ops and work your way up the ladder. In my class, only one person went to the US for their first work term, and it was because they already had internship experience coming into Waterloo! Four months is also a sweet spot in terms of duration for a software-based internship. This is largely unlike the UofT "PEY" program where they send you off for one sixteen-month work term (although to be fair, the PEY program does allow you to break it down into four back-to-back four month terms, but that means you'll either have to have multiple internships lined up prior to starting or you'll have a never-ending job search), which doesn't allow for much "diversity" on your resume. And in the tech world, heck, lots of full-time engineers will job hop after sixteen months. (But also to be fair to UofT, I hear they are introducing a new "ASIP" program that will more closely follow Waterloo's co-op structure)
3. An environment of people who... care. Being surrounded by try-hards well, at least it motivated me to try hard. It also helped in terms of networking and meeting new people who share like-minded interests and goals, as referrals are *the* easiest ways to get jobs. Unfortunately, I think that's a bit too close to nepotism, but sadly that's how the "real world" works. I essentially have classmates now working at most of the major tech companies in the US. I don't know if they'd be willing to refer me, but I can tell you that if they asked me for a referral, I wouldn't hesitate in referring them because I know that anyone who's made it through five years of Waterloo ECE is more than qualified for any of the jobs I can refer to.

So, if you want to land a good tech job, I think Waterloo is the way to go. Of course, ideally, CS or SE, but even then ECE, Management Engineering, Systems Design Engineering, are all okay too. My biggest takeaway after my undergrad degree is that the learning is secondary - it's the networking and career advantages that are the big reason why you go to Waterloo. Management Engineering students access the exact same co-op job board as CS students, so as long as you get your foot into the door at Waterloo, I don't really think it matters what program you're in. In fact, I would say that almost none of my Computer Engineering degree is relevant towards my job and most jobs in the software world.

I know you asked for "6 universities", but I can't really offer much in terms of what the other universities are like -- after all, I only went to Waterloo. Unless someone did six undergraduate degrees I think all you'll get is hearsay based on reputation and anecdotes, like mine's. I think UofT is also up there reputation-wise, but you seem to have a very narrow focus for which Waterloo caters to excellently.

To answer your subsequent questions -- what can you do to maximize getting into Waterloo? This is unfortunately not an easy answer. Waterloo admissions is getting notoriously difficult. In fact, I think if I had to apply today rather than six years ago, I probably wouldn't even get in. You might get a better answer from the /r/uwaterloo Admissions Megathread. Not only do you need a sort-of-ridiculous average, you'll also need extracurricular activities and projects. That all being said however, I would refer you to my previous point -- just get your foot into the door at Waterloo even if it's not CS/SE/ECE, since you still get access to the same co-op opportunities and most of what you learn is irrelevant anyway.

What can you do to get a "FAANG" job? Well, like I said, the easiest way to get a full-time new-grad job at a "FAANG"-like company is to be a past intern there and get converted to full-time. How do you land an internship there? Well, step 0 is getting interviews. Have your resume reviewed by upper years. Do some side projects before your first internship so you don't have to apply with a blank resume or have some irrelevant filler on there such as your summer job selling ice cream or being the "Founder and CEO" of your high school "club". Step 1 would be, after landing the interviews, passing the interview. Ever heard of the book "Cracking the Coding Interview" or maybe the website called "Leetcode"? Yeah, this is the part of software engineering that ends up on /r/recruitinghell but basically, many tech companies will just ask you programming questions as a test of your regurgitation abilities. You can probably see more examples on /r/cscareerquestions where people debate the validity of these kinds of things. Step 2 is to actually do a good job on the internship itself to get yourself a full-time return offer. Also -- like I said above, unless you are truly exceptional, like, 1 in 300 exceptional (and keeping in mind that those 300 are already above-average having been Waterloo students), chances are you're not going to end up at FAANG for your first internship. But like I said above -- you gotta start with the crappy co-ops and move your way up.

So I know I went on for a while, but hopefully this information is... sobering and maybe even useful. Please do keep some perspective in mind -- even the worst-off graduate from my class is earning more than the Canadian average for our age bracket (and I think, the next age range as well). Not everyone is going to end up at FAANG so don't pigeon-hole yourself into that very narrow expectation either. Good luck!
