Subject: Seeking Advice on Follow-Up After Interview Invitation

Hi everyone,

I applied to a large company at the end of November and used their online application system to track progress. After I noticed my application wasn’t moving, I reached out to the main recruiter last Monday. To my surprise, they responded just a couple of hours later, inviting me to schedule an interview and asking for my availability for this week.

I replied within an hour with my available times, but I haven’t heard back since then. Now that it’s the new week and the interview was supposed to be happening, I’m unsure of the best next steps. Should I send a follow-up email, or perhaps message the recruiter on LinkedIn, since I found him there? Or is it better to just wait a bit longer?

I would really appreciate any guidance.

Edit: I remembered that I sent a follow-up email the day after confirming my availability.
