Almost 24 hours ago, I submitted an application for an engineering job through that company's email using a resume template that I used when I was applying for internships as a 3rd year university student (I am a recent graduate). It was a 2-page resume and some of my relatives who worked in HR said that it was too long and looked like a student resume. I have made some changes and shrunk it down to 1 page. Should I resend my application and hope that my old application was unread, and my new application would cover my old one?
No you shouldn't.
2 pages is not excessive. It may be longer than the "optimum" length of resume, but it's very unlikely your resume will be thrown out just for being 2 pages. On the other hand submitting a resume a second time looks unprofessional - as though you had forgotten you had already applied for this job.
It is also making the company do extra work - they need to realize that you applied twice, go and find the original resume and delete it from their applications. Since the point of short resumes is not to make the recruiters do extra work, submitting two resumes defeats the original point.
If you re-send an application, this company will now have received in the span of 24 hours two applications from you with two separate resumes. This will likely make you look like a disorganized and unprepared candidate and can hurt your chances of being considered for the role.
Should I resend my application and hope that my new application was unread and my new application would cover my old one?
Personally I would not send a new application. Also, I don't know why you would hope that any of your applications was not read. If they don't read your first one, what guarantee is there that they read the new one? And why would you want to work for a company that can't do something as simple as reading all the applications for their open positions?
If the CV is up-to-date with your studies, experience, and profile, and you’re not aware of any serious mistakes on your resume, including any gaps, then do not re-apply for the same position and vacancy, especially within 24 hours after submitting your original application. It can confuse their hiring team or even make you look unprofessional. Regarding the resume’s length, the suggested page number is 2 pages maximum. But my CV is 5-6 pages, but I’m more comfortable in having a long CV than having gaps which might raise unnecessary suspicions. I’ve had interviewers praise my CV, describing it as well written and my profile well-described, and was never given any negative feedback due to its length by them. It’s a matter of opinion and it goes both ways (the job applicant and the hiring personnel).
Should I resend an application to give a shorter resume?
No, this would cause more issues than it would solve.
The only time I've ever sent a second resume for a single position is when a recruiter asked for a resume tailored to the job position.

If you're applying for a frontline fast-food position then 2 pages is unusually lengthy, yes.
Engineering though, 2 pages seems about right. Length has never been a reason for me to reject a resume. However, if I skim it and it's 5 pages of crap then it does go in the garbage.
If your relative is putting this much emphasis on resume length then they are probably bad at their HR job.

This, this is an actionable item. If your resume is crafted like a newbie then you will be labeled as one.
