This is a problem in general. There were so many instances where the candidates were turned down because they couldn&#x27;t write an algorithm from text book. The famous example being the guy who made Homebrew.<p>Reasons are below:
1) The existing assessment methods being used have been working for companies except in some cases.
2) There&#x27;s no new way(yet) to assess candidates apart from the experience related questions. some companies use pair programming interviews which is by far the only different way which seems to be working.
3) Companies don&#x27;t have time&#x2F;resources to screen every candidate over phone, so they end up sending a link to hackerrank or some other programming questions site. And there are no custom assessments generated based on the candidate profile, rather these are very generic aptitude&#x2F;algorithmic questions.
