Our interviews are modern
Litebulb interviews look like everyday dev work. Whether you’re looking for a frontend, backend, or full stack engineer, we have the interviews you’ll need. If we don’t, we can create one for you!
Realistic Interviews
Litebulb interviews are simulations of regular dev work. Candidates are given production databases, web servers, and apps and build real features.
Familiar Experience
Interviews are hosted on browser-based VSCode IDEs, setup is instant, and everything is on Github, so candidates feel right at home in a Litebulb interview.
Modern Reports
Litebulb reviews submissions how a senior engineer would review a code change request. We test for edge cases, performance bottlenecks, scalable design, and code quality.
Reduce Bias
Every metric we measure is numeric, and every test is deterministic. As a result, you can make hiring decisions based purely on merit.

Frequently asked questions
What kind of interviews do Litebulb offer?
Litebulb interviews are in the form of take home challenges or onsite interviews (remote or in-person). We currently support three popular engineering tracks:
1. Full Stack Web Engineer
2. Frontend Web Engineer
3. Backend Engineer
As our interviews are multi-tech stack, each interview is some combination of a few of these technologies:
1. Javascript/Typescript
2. Python (Django or Flask)
3. Node.js + Express
4. React.js
5. Golang
6. Ruby on Rails
7. Java Spring Boot
8. Docker
9. GCP or AWS
10. MongoDB, MySQL, or PostgreSQL
We are actively expanding our list of interviews, and are more than happy to partner with you to build interviews that make the most sense for your team!
How long do Litebulb interviews last?
Projects take anywhere between half an hour to several hours to complete, Litebulb gives recommendations depending on level of experience. As an employer, you can choose to send Litebulb interviews out as take-homes over a few days, or conduct them as a remote onsite over a single sit-down call. Ultimately, you have full control over how long candidates get to complete the interview.
Do you interview our candidates face to face?
The Litebulb team does not interview your candidates face to face. Rather, we provide you with the environment and tools to allow you to easily interview your candidates face to face. Leave the code evaluation to Litebulb, and you can focus on getting to know your candidates better and gauging their cultural fit.
How does Litebulb’s auto-evaluation work? Can I trust it?
Litebulb’s auto-evaluation isn’t anything fancy or nebulous. In fact, we intentionally don’t utilize any AI or NLP technology. Our evaluation is simply a long list of true or false statements about someone’s interview submission. Here are some examples:
1. We expect this “Cancel” button to close the popup, if we click on it, does it close the popup?
2. We expect that running this API call with a specific ID returns a specific item, does it?
3. We expect that all newly added identifiers in this commit are in camelCase, are they?
4. We expect that running the linter should produce no warnings and no errors, does it?
The purpose is that Litebulb’s evaluations are 100% deterministic, so there won’t be any questions of accuracy. The only question remaining, what if I want to test for something that Litebulb doesn’t currently test for? Then you should email us at info@litebulb.io to see how we can add these tests in!
How do you prevent cheating?
All interview submissions are automatically checked against previous submissions of the same interview, so any time we find a suspicious match, a ticket is created and we manually investigate the case. Any interview that is deemed to be widely leaked will be deactivated from future use on the platform, and any candidate deemed to have leaked the project will be banned from the platform.
How much does this cost?
Contact us and we’ll let you know about our pricing plans!
What if Litebulb doesn’t have any interviews similar enough to our tech stack?
If you use particularly rare frameworks or libraries, it may happen that Litebulb does not have any interviews that relate close enough to what the role needs. If this is the case, send an email to support@litebulb.io and our team will be happy to work with you to create a new project within your relevant domain and stack!
Do you offer any support?
Yes we do! Our support team is available from Monday to Friday, 9:00AM to 5:00PM PST, so any time you have a question or need help with something, you can reach us at support@litebulb.io and we’ll be happy to help!
