Hire the best Developers

Don't waste time interviewing developers who aren't suitable for the job. Find out quickly how well someone can code. With Interview Zen, you set your own programming challenges and watch how candidates solve them online.

Capture the candidate's thought process and problem solving speed. See how they structure and revise their code over time. Evaluate their programming ability before you invest time in a face-to-face interview.

        else if(i % 5 == 0) printf("Buzz\n");
        else if(i % 3 == 0) printf("Fizz\n");

3 Simple Steps


Create the questions you'd like candidates to answer. Be as creative and job-specific as you like.


Invite candidates individually or post the interview link on a job board and let candidates come to you.


Collaboratively review the recorded interviews. Save time and money identifying the best developers.


Example question: Write a program that prints the numbers from 1 to 100.
But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz".
For numbers which are multiples of both three and five print "FizzBuzz".
