I’m currently employed full-time and I recently received a confirmation email for a job that I applied to. However I have not yet received an offer letter. Should I resign from my current organization?
No, you should not resign from your current organization without first receiving an offer letter from the new organization. The confirmation email is not an offer letter, and therefore does not constitute a binding offer of employment. If you were to resign from your current organization without receiving an offer letter, you would be doing so without any guarantee of employment from the new organization.
