Red Flag for a Detail-Oriented Position?

We have a candidate who has received an endorsement for another interview. After sending her an email with the interview invitation, I didn’t hear back for over a week. She eventually contacted one of the recruiters for an update, prompting us to resend the original email. Following that, she booked a time, which automatically generated a confirmation with the date, time, and meeting link, sent to both her email and Google Calendar.

Despite this, she continues to reach out asking when the interview is, what time zone we’re in, and for the meeting link again. Though we haven’t met yet, I am concerned about her ability to handle basic email details, which is essential for a detail-oriented role. Do you think I am justified in my concerns?
