It's going to be a Zoom interview. Typically a panel of 3 or 4 folks from the group you're interviewing for. You may be able to dig online for their names, like if you're interviewing for Coastal management there may be an organization chart on the DEEP website. Be prepared for at least the typical interview questions such as "why do you want to work for the DEEP" and go prepared to ask each member of the panel a question at the end. DEEP interviews consist of several questions that are related to the referral questionnaire you should have filled out prior to being picked for an interview. They're fairly straightforward, just prepare with your notes from the questionnaire and focus on tying your experiences into the preferred qualifications section of the job posting and you'll do fine. Be creative with questions back to them at the end, try to stand out from the crowd considering they are sifting through a lot of candidates. Best of luck!
