Tech tests are bad practice in hiring process

• It shows that the company does not trust the candidate
• They don't care about whatever the candidate says on their CV/Resume or interview
• If they can put together a test and a way to evaluate it then they already have the time and skills, why do they need to hire someone?
• Giving tests automatically means anyone without any qualifications or experience can apply as long as they pass the test. You can even give a test to a janitor and if they pass they qualify for the job?
• It means a candidate experience is worthless
• It means a candidate academic qualifications are worthless
• When the interviewer says they are looking for high caliber people in order to justify a tech challenge it automatically implies they discredit your background so what is the point to a CV/Resume and interview?
• It already shows the way the company will treat you as an employee with suspicion, hostile contempt, and disrespect
• Can't form relationships based on distrust
• What is the point, the candidate has likely taken tests all through their life in school and university, while also working on complex projects, do they really need to be put through the paces of more unnecessary tests?
• Testing bookish skills is not really very constructive approach. Often bookish skills get learned and relearned on the job. And, organization should be really looking for astute candidates that can adapt to change. A better approach is to expect candidate to elaborate on the project details like drawing the entire diagram about the things they worked on where their interests can be seen. Someone that has the experience will know inside out in minute detail about the implementation, shortcomings, and learning experience they had. This will be more valuable for an organization than a silly bookish test. Case studies are also a more constructive approach. In fact, discussion or a deep dive on an approach is also a more constructive approach while making the candidate feel comfortable, engaged, shows their personality, and enthusiasm.
• It is likely to make the candidate reluctant to spend significant time doing it, especially if the organization takes advantage of their skills for free from the solution.
