Is This a Red Flag for a Detail-Oriented Position?

We have a candidate who was recommended for an interview, but I’ve encountered some concerning communication issues. After sending her an email with the interview invitation, I didn’t receive a response for over a week. Eventually, she reached out to one of our recruiters for an update, prompting us to resend the initial email with all the details.

She then scheduled her interview, receiving an automatic confirmation that included the date, time, and meeting link, sent to both her email and Google Calendar. Despite this, she continues to email us asking about the interview schedule, time zone, and requesting the meeting link again.

Although we haven’t met yet, I’m worried that she may not be a good fit for the role, as she’s struggling with basic email management—something that’s essential for a detail-oriented job. Am I right to be concerned?
