Insights on Candidate Selection

Hello, recruiters! I’m curious to know what you consider the most significant time-waster in the recruitment process.

For instance, if candidates turn out to be a poor fit for the position several months after hiring, what do you think contributed to that situation?

I suspect that interviewing candidates to gauge their personality and passions could be a major bottleneck. Perhaps focusing on selecting the right candidates to move forward in the screening process is the key to reducing delays? What are your thoughts?
