Days of Code

Discover True Professional Freedom. Learn to Code.

Thousands of people have improved their lives by learning how to code. You can too!

Days of code Rotterdam, NL

Days of Code is a revolutionary way to learn how to code. During our 10 or 100 day events, participants learn new skills by building their own projects. By making use of custom selected online materials, a group of encouraging peers and a mentor, learning is efficient and fun.

One could say that Days of Code is the opposite of distance learning – we are very close learning. Coding events are full-time in person learning. Students learn 60% by self study, 30% peer to peer and the last 10% from their mentors. This means that graduates are independent, good collaborators and by definition learners for life!

100 Days of Code

September 2018

Diving is one of the most magical sports on the planet. We always see the beautiful stretching out. The silence. The immence concentration. And then... the jump. What we did not see, is the months, even years it took to prepare for that one moment.

You are here now and we don't know your story (yet). But somewhere in your life seeds were planted. People told you that you were talented (or not). You were promised beautiful things in life. Some of these promises came true and others did not. Hundreds of event in your life, big and small, have brought you to this moment. You were promised a beautiful career. And now you are here. Just like the diver. And the question is: are you ready?

Days of Code strives to offer a high quality education at affordable prices. The cost for attending days of code is:

100 Days of Code: free!

I don't understand... how can you offer this without charing?

We try to combine a bunch of things (including volunteers, using existing online materials and charging a placement fee) to enable us to offer you a great education without you paying. That doesn't mean that your education is free though, just that we won't charge you.

Application Process

We select students based on three criteria: Ability, Attitude and Commitment. Our application process is simple: Four easy steps and your in!

We are using a rolling application process: students apply and are continuously accepted based on our selection criteria. This means that the earlier you enroll, the larger your chances of getting accepted: once all spots are filled, enrollment closes.

Step 1: Form

After you've decided to join for 10 or 100 Days of Code, please make sure that you are able to join for the entire course. Our coding events are full time in person learning. Ready to commit? Start your application here:

100 Days of Code

Step 2: Pre-work

You will be assigned pre-work based on your ability and experience. Don't worry if you are a complete beginner, we will make sure that your assignment is suited to you. You will never feel overwhelmed, just make sure to dedicate the time required for your pre-work. For 100 Days of Code a commitment of 40 hours is expected

Step 3: Interview

Once you've completed your pre-work, you'll schedule an interview with our student recruiter. You will talk through your pre-work and figure out a great project for you to work on. This is not a technical interview - you've already proven your ability and commitment by completing the pre-work.
