  • How does an online career fair work?
    Our online HVAC career fair works just like an in-person fair, but online. Each company has a zoom room that you can join to ask questions, do an interview, or hear more about the company. The best part is that you can do all of this from your home! No booth lines, packed rooms, or travel time.
  • How do I get hired and send in my resume?
    Resumes are the old way to find a job. After you register for the career fair, fill out your profile. From your profile, employers will be able to see your schooling, experience, and skills! What is more important is the SkillCat assessment. It will test you on your HVAC skills and provide recruiters with a detailed summary of your ability. Do great in the evaluation, and your job prospects will look great!
  • Who is this event for?
    The online career fair is for companies and workers in the HVAC industry. We are mainly focusing on HVAC technicians since they are in such high demand right now. Still, companies will be hiring for other HVAC positions as well!
  • How will I talk to recruiters during the event?
    Each company will have a zoom room, which will remain open during the event. You can pop into a room at any time during the fair to talk with the recruiter. Companies will also be hosting 15-minute presentations throughout the fair if you wanted to learn more about them.
  • Is there a schedule for the event?
    Yes! The event is from 9 am - 3 pm PST. From 9-10 am, there will be an introduction and talks from two keynote speakers. At 10 am, the conference will break up into over 25 different rooms. A recruiter will host each room. Pop into the rooms that look interesting to you and introduce yourself to the recruiter. Simple as that! From 12-12:30 pm PST, there will be a short break. After that, we will split into rooms again, and that will go until 3 pm.
  • Do I have to attend all 6 hours?
    It is excellent if you can attend all 6 hours, but no, you don't have to stay the entire time. We created the career fair so that you can join and leave rooms at any time. The flexibility of Zoom rooms lets you explore companies or take a break if you need one.
  • Can I join the conference on my phone?
    Yes! The conference will be hosted over zoom. All you have to do is download the zoom app before the event, and then click the invite when you want to join. We recommend joining with video on, and your microphone muted. Muting your microphone prevents unwanted background noise, but unmute it whenever you have a question or want to talk!
