Last Sunday I saw a job announcement on a recruitment website and emailed a cover letter together with my CV directly to the prospective employer. The employer is a private school in the city I currently live in, and the job is a well-paid teaching position.
At noon on the next day, Monday, an HR officer of the school sent me a one-line email saying that they were interested, and asking me as to when it was convenient for me to come for an interview.
I saw her email a few hours after it was sent, and got puzzled as to why she couldn't just call my mobile phone number, which I had provided both in my cover letter and the CV. Furthermore, her email did not contain any phone number I could reach her by. She only provided her name and position, HR manager. I then checked the school website, but was unable to find there her phone number or any phone number of HR.
So I sent her a one-line response by email, saying that this week I could come at any time starting from Wednesday and that I could not come earlier.
Some hours later, Monday late evening, I checked my email box again and found her response, which had been sent to me a couple of hours after my response. Again, her email was just one line. She said she could offer me Thursday this week 11am and 3pm. And, again, there was no phone number.
Seeing that response, I instantly sent her one line, "Great, let's make it on Thursday at 3pm then, okay?"
Receiving no response to this, I sent her a short follow-up email on Wednesday at 3pm, asking her whether she could confirm Thursday 3pm.
Now it is Wednesday evening, and I still have not heard anything from her. And yes, I have checked the spam folder.
What is going on and how should I handle this? Is there anything I did wrong? Are people nowadays supposed to be always online and instantly answer emails? I check my email box 2-3 times a day and am often away from my computer.
