I&#x27;ve referred people senior to me and been told by the recruiter that it was significant.<p>Because I can&#x27;t be expected to know their work as well as they do I describe their peers&#x27; opinions (well-respected in the NOC) and the soft-skills they have like mentoring, etc.<p>&quot;Even though I was only an SDET, Dave took the time to help me fully understand the math involved in the problem domain and how to efficiently model it. This allowed for a 60% increase in my deliverables and put the entire team a week ahead of schedule.&quot;
