I was invited for an interview, and they asked me for my availability within the next three days. However, they did not bother to schedule an interview in those three days. I waited for another 2-3 days to hear back from them, but did not so I sent a follow-up email. I gave them my availability again for the next few days, and this time again they did not bother to schedule an interview. Both the times they specified the dates for which I provided my availability. Both the times they did not deem necessary to contact me to ask for additional availability if, for some reason, they were not able to schedule an interview. I was disappointed by this and just withdrew my application.
