About the interview

Interviewing for a Software Role at Quazel

Hi 👋

Hey there! We're Quazel, an ETH Zurich spinoff and YC W23 startup. Our mission is to make personalized education accessible to everyone through our AI language tutor. If you share our passion for edtech and have a strong background in front-end development with React and/or React-Native, we'd love to hear from you! Send your questions to philipp@quazel.com.

At Quazel, our core values are playfully ambitious, transparent & respectful, no bullsh*t, flat hierarchy, and pride in building high-quality products. These values are crucial to us, and we're seeking like-minded individuals to join our team.

The Interview Process

Video Call: Getting to Know Each Other

Our first interaction is a friendly and informal video call where we chat about your past experiences and get to know each other. You can expect a light technical question related to your past projects. The aim is to understand how well you can work autonomously and if you're the right fit for our team culture.

Technical Onsite: Showcasing Your Skills

The technical interview, led by Dave, will dive deeper into your past experiences. Depending on your expertise, you may be asked to:

  • If you're a frontend developer, code a simple React component and redesign a screen from our app.
  • If you're a full-stack developer, answer backend scalability questions.

The goal is to evaluate your problem-solving skills and ensure you're up for the challenge.

Behavioral: Finding the Perfect Fit

Sam will lead the behavioral interview to assess your cultural fit within our team. We're looking for candidates who are authentic, open-minded, have the ability to admit when they're wrong, and can collaborate effectively with others. We love people who are funny, ambitious, and not afraid to call out bullsh*t when they see it!

The final one: Experience Day ✨

The experience day is a unique part of our hiring process at Quazel. We invite potential team members to spend a full day with us, experiencing our day-to-day operations and our unique work culture.

During the day, you'll be given a brief assignment related to your potential role. This is an opportunity for you to showcase your practical skills, not just your theoretical knowledge.

You'll be working independently, mirroring the autonomy you'd be given as a member of our team. Our aim is to see how you manage your time, how you approach problem-solving, and your overall coding and development style.

Lunch is a collective effort at Quazel, and you're invited to join us. We believe in taking the time to step away from our screens, chat, and enjoy a meal together. It's a great opportunity to mingle with our team in a casual setting, ask questions, and let your personality shine through.

At the end of the day, we can grab something to drink and chat some more.

Through the Experience Day, we aren't just assessing your technical skills--we're also evaluating the fit between you and the rest of the team. We believe successful collaboration stems from people feeling comfortable and connected with each other.

Remember, the Experience Day is as much about us getting to know you as it is about you getting to know us. We want you to walk away feeling excited about the prospect of joining Quazel, so don't hesitate to ask any questions or voice any concerns.

Timing: Results in No Time!

At Quazel, we're fast-paced, and our hiring process is no exception. Depending on your availability, the entire interview process may take approximately 2 weeks. We'll keep you updated every step of the way.

We're excited to meet you and hope to embark on this thrilling journey together. Good luck!
