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
