March, April and June applicants.
It looks like the above-mentioned are the same ones who got the random email in June and for some reason haven't received their invitation email. My patience had worn completely thin by last evening, so earlier this morning I gave HR a call. It took quite some time to get through but I eventually did and the response I got was least helpful, in my opinion. The lady sternly explained to me that it was against company policy to disclose their recruitment procedures. So she "reassured" me that the process is free and fair since it's done online and that I should be patient. She also said that she'll pass my concerns to the people concerned with the shortlisting.
My prayer is that they're calling in batches and that we'll be invited by Friday. I can't imagine having to wait some more months for the invite! Let's keep hope alive!
