Screen candidates early in the hiring process

Bytes Screening Tasks

Our Test-Driven Development (TDD) approach to screening invites candidates to write code against predefined tests, ensuring a seamless evaluation of their problem-solving and coding prowess.

Test-Driven Development (TDD):
More realistic than algorithmic puzzles. Candidates write code against predefined tests.
Automated Evaluations:
Receive a report on passed and failed tests, along with the candidate’s code and commit history.
Natural candidate experience:
