Quitting a job I just started

Hey guys. I started a job in February and it’s been awful. Things quickly changed and they lied to me about some key things. I know to do my due diligence a lot better next time. That being said, I am interviewing actively for multiple positions (at least 10-15, 6-7 are 2,3,4 round interviews) some are about to be an offer... should I quit my job or wait until this is concrete? Also, I’ve only been there a month and a half, is it terrible to not give notice? I feel like it’s kind of stupid to put in 2 weeks when I’m still learning and not doing much.
