Choose the window based primarily on readiness and any real deadline you are managing. There is little value in taking an earlier interview if the extra time would materially improve your case and personal-experience performance.

Treat the invitation as positive only in the basic sense that the firm wants to interview you. Do not infer a special scoring advantage or lower interview bar from the timing.

The exact sequence varies by firm, office, and candidate type, but the common structure is application screening, any required assessment, one or more interview rounds, and then a final decision. Some candidates also have recruiter conversations before interviews.
