  • Use diversified questions from varied Javascript topics to test the skill range of candidates
  • Utilize questions of different difficulty levels to test candidates
  • Include questions that are related to on-the-job skill requirements

  • Use aptly timed assessments that can be fulfilled within 45-60 mins to make the most optimal use of the time utilized

Don’ts

  • Avoid using trick questions to test the candidates as they are ineffective in testing their on-the-job skills
  • Avoid using lengthy questions as they do not provide an ideal scenario to test the candidates
  • Avoid unnecessary puzzle trends as they are ineffective in assessing the skills required for the job
  • Avoid questions that test very niche concepts that a strong candidate might or might not have come across on-the-job
  • Do not include unnecessarily difficult questions that might or might not test the candidates potential
