Do’s and Don’ts of selecting Java questions for assessments:
Do’s
- Use diversified questions from varied Java 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
- Pick questions that are relevant for the experience level you are targeting
- Make sure the questions can be understood by a non-native English speaker (easy-to-read questions because programmers should spend time solving the question, not understanding it)
- Ensure that the questions have a granular (non-binary) scoring
- 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
