Interesting question Veena Venugopal but there is no silver bullet answer to this one. There's simply too many unknown variables employers don't typically publicize during the recruiting and hiring process.

I've been told that a typical entry level job opening can take an applicant 6-12 weeks from online application to first day on boarding orientation while other companies might host an on the spot hiring event where an applicants first day is within 24-72 hours from application completion.

Try not to look at getting hired in terms of time (timeline). Focus on getting noticed first. That's a very big challenge among job seekers today.
