How many people should be interviewed?
As a general guideline, we suggest you meet with 3-5 candidates in the first round of interviews, and 2-3 in the second. If you are interviewing more than these, it may mean that you are not qualifying your candidates sufficiently prior to the interview.
How many people should I interview for a research?
Starting with 5 users is still a sensible choice, but be prepared to conduct further research with additional people, potentially as many as 8-15 different users, and sometimes 30 or more.
