A lot of information will come from the interviews, and you may forget who said what. So keep a record of what you learned from the applicants. For instance, you may discover that Joe knows COBOL, speaks Spanish, and has supervised 6 people; whereas Lynn has worked 3 years with COBOL, knows conversational Spanish, and has supervised 12 people.
Intangibles are more difficult to note. Stay away from vague comments. List specifics. Instead of observing that Joe is creative, list examples of his creativity in previous jobs. If appearance is a job-related factor, don’t write sloppy or rumpled. Those comments are subjective. Note, instead, “clothes unpressed, dog hairs, shoes not shined.”
Personality factors may also be important to the final decision. Once again, avoid subjective comments. “Applicant appears to lack self-confidence,” is an opinion, but the statement, “Applicant looked down at the floor during the entire interview and was hesitant in answering questions,” is a fact.
Wait until after an interview to record the information you discovered about the candidate. Give yourself 10 to 15 minutes between interviews to summarize your impressions.
