This is what I did to ace the Toptal interview

On how to best prepare and what to expect from the screening process

A few years ago, I wrote an article on how I got into the most exclusive remote work platforms and it got a fair amount of attention. Since then, I’ve answered the same question all over the years: “How can I get into Toptal?”. I’ll try my best to give you some tips on what to expect and how to prepare.

What’s Toptal?

For starters, Toptal is a remote work marketplace which claims to only accept 3% of the applicants. As such, the work quality and the rates are much, much higher than other platforms like Upwork, Freelancer, Freeeup, you name it. There are some other top platforms like CrossOver, BairesDev, Number8, Pilot or Turing which also claim to hire the best of the best. After passing on most of these (not bragging, just helping), I can honestly say the toughest interview has been Toptal.

Apply to Toptal with my referral code and we both get 500USD once you land your first job:

I’m sold. How can I get in, then?

Clearing the screening process is exhaustive. It takes a lot of your time and energy but, believe me, it’s totally worth it. Apart from writing a killer resume, I’m going to lay out the main points I’d recommend to anyone willing to apply.

1. Do your research

Toptal hires for roles in Software Engineering, Product and Project Management, Finance and Design. My first recommendation is to look online for interview stories on these roles. See what others have gone through while applying to Toptal. There are hundreds of testimonials on the technical interview and the test project for all of these roles. If you can’t find any resource for your role, then try looking for the same in any other FAANG company. The process will likely be similar.

2. Communication is king

As of April 2020, I’ve referred short of 130 people into the platform and only 3 of them have passed. I’d say 75% of those who didn’t clear the process were filtered out in the very first interview. They call it the “language and personality” interview. This is nothing else than just a screening phase to see how well you communicate in English. I’ve seen many of these interviews myself and the bar is pretty high.

You definitely don’t need to be native-fluent or have crystal clear pronunciation. The trick is to communicate as clearly as possible and be able to effortlessly talk about yourself and your experience. Do not sound rushed. You must practice your English speaking skills regularly before taking your shot at Toptal, or in general at any of these top remote work companies. If you’re not fluent in English, but you’re dead serious about improving, you’d be spending by now 3 hours a day (from 5-8am) studying, practicing, speaking with yourself out loud, repeating everything you hear in movies, etc. This is definitely a very restrictive filter in the process.

One last thing: put up a smile, look friendly (even if you are not) and set up a good space for the interview. It’s been scientifically proven we humans favor friendly people over serious, rude looking folks, regardless of the role. It’s also fine if you disagree with this notion, take your chances.

3. Let’s get technical

This section is mainly aimed at Software Developers. To put it down in simple words, you need to be good at algorithms. Sure you don’t practice that in the job, sure you don’t need it to create a React app or a Go backend, and sure you can be a great engineer without those skills. All of them valid points I also agree with. But, sadly, acing an algorithm interview is a very common requirement to get into these platforms (or any other big tech company). You either suck it up and accept it or give up and move on. It’s like being good at sales, design or cooking - you can get through life without those skills, sure, but wouldn’t you be better if you take a stab at them?

Now, as with everything, you just need a lot of practice. Don’t compare yourself with chess masters or mathematicians that can solve any coding problem in 10 seconds. Good for them, but that’s probably not you, or me. I’ve put an insane amount of hours studying for technical interviews (Toptal, Amazon, Crossover). The recipe is simple: get yourself a copy of Cracking the coding interview, sign up for LeetCode and Hackerrank, and commit to put 2 hours a day, for 2 months, solving algorithms.

Now, let me be more specific. For Toptal you won’t probably need to master graphs, linked lists or trees. I’d recommend you to focus on solving between 70 and 150 problems tagged as easy in Hackerrank and Leetcode. This will involve working on problems with strings, sorting, search and, why not, a bit of recursion.

As a fun exercise, try solving Repeated String and Minimum Distances in Hackerrank. That’s somewhat similar to what you’ll find in the interviews. Don’t apply to Toptal if you can’t still solve these 2 problems - it’d be a missed shot for sure. Don’t be discouraged, though, it’s all about practice, practice, practice.

4. Time to show off your true skills

Let me be honest. If you clear the 2 previous algorithm filters, you pretty much passed already. The last step in the process is to build a project with the skills you need for the role. You’ll have 2 weeks to solve a problem you’d normally find in your daily job.

For designers you’ll probably be asked to deliver UI/UX sketches for an application; For web developers you’re likely to submit a full-stack project with authentication, decently looking frontend UI, unit tests, good DB management; For Machine Learning be prepared to hand off, for instance, an end-to-end supervised learning project with data analysis, model implementation and perhaps deployment; and, for Product Management, I won’t be surprised if you’re asked to define the roadmap for a new product, evaluate pros and cons, design wireframes or even do some mock team planning.

This is the time to show off the experience you’ve built over the years. You’ll need to demonstrate your expertise in the final interview as they will ask you a ton of things about your project. Most of the companies at Toptal are willing to pay very well for experts, but you need to believe and act as if you’re one of them.

Why only Toptal?

Let me tell you what, I used this same preparation to interview and get a job offer from Amazon. At some point, you’ve just put such a huge amount of work and study that you don’t need any Toptal to revalidate your learning, you’re 3% already. You have what you need to apply to any other top remote marketplace. It will increase your chance to work remotely for US companies with salaries you can only dream of now. I’ll suggest some platforms below but I don’t know them all. Ping me on Twitter and let me know if you know more:
