In-person Interview: To ensure health and safety, we are reducing the number of in-person interviews during the current increase in Coronavirus cases. We expect this change to result in increased wait times when visiting us in person and strongly encourage you to take advantage of our convenient virtual and phone interview options. If a virtual or phone interview does not meet your needs, we encourage you to call (714) 347-4980 before you come to your in-person interview so that we can prepare for your visit and share current wait times. As a reminder, a mask covering your nose and mouth must be worn throughout your interview.
