FAQs

How are Toptal JUnit developers different?

At Toptal, we thoroughly screen our JUnit developers to ensure we only supply experts of the highest caliber. Of the more than 100,000 people who apply to join the Toptal network each year, we accept fewer than 3%. You'll work with engineering experts (never generalized recruiters or HR reps) to understand your goals, technical needs, and team dynamics. The end result: expertly-matched talent from our network, hand-selected to fit your business needs.

What is the no-risk trial period for JUnit developers?

We make sure that each engagement between you and your JUnit developer begins with a trial period of up to two weeks. This means that you have time to confirm the engagement will be successful. If you're completely satisfied with the results, we'll bill you for the time and continue the engagement for as long as you'd like. If you're not completely satisfied, you won't be billed. From there, we can either part ways, or we can provide you with another expert who may be a better fit and with whom we will begin a second, no-risk trial.

How fast can I hire JUnit developers through Toptal?

Depending on availability and how fast you can progress, you could start your no-risk trial with a JUnit developer within 48 hours of signing up. Most of our engagements start within 2 weeks of discussing your project with us.
