I applied online for the Software Developer, Community Operations Engineering role (Dublin) and, after some time, received an email from a recruiter. We had an HR phone screening, after which she asked me to send my availability. She requested that the interview be arranged not later than two weeks from that date. During those two weeks, I spent several hours every day preparing well for the interview.

However, to one of my emails, I received only: "This email account is inactive. Please contact another person at the company." As a backup, I was given the email address of another HR specialist, whom I believe was her manager. I wrote to that email address, as I obviously didn't know any "another person" working at FB. I did not hear back from her either.

I did not expect to encounter such a disdainful attitude toward candidates and their time from such a reputable company. But if this is the normal attitude that corresponds to the company's culture, I am glad I am not working there now.
