  • 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 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
