I deal with a relatively high volume of applications/resumes per day.  What ATS do you use?  We use ExactHire and it makes screening applicants a relatively easy process. I usually screen anywhere from 10 to 40 per day (just depends on how many have applied). 

Any applicant I want to potentially interview, I  call  (and/or text or email if they don't answer), ask any further screening questions, and then try to schedule a Zoom interview with them at the earliest convenience. 

Feel free to reach out with any further questions you may have.

Calendly is a solid/easy free tool for giving the candidate the ability to schedule themselves based on the parameters you set. Define screen in a day? Are you referring to reviewing new applications/CVs or conducting phone screens? 

I'll try to answer both. Typically I think 6,7 phone screens per day represents the average recruiter and avoids burnout. At roughly 30 minutes per screen, that alone represents 3-3.5 hours of their day. I think a strong recruiter can review 100 job applications per days. Using an average of 20 seconds per review, that should take about 30 minutes of time. Those 2 functions would equal 50% of their day, roughly 4 hours.

Leaving time to source, connect with hiring managers, extend offers, etc.
