I do not question the interview; it is their way of doing things, but the feedback was neither constructive nor open. The Talent Acquisitions team got back to me and reached out to TA to give more details. The hiring team is not organized because they could not set a time for weeks, even though I provided several options. They do not have modern tools to help schedule interviews.
