“Also, some companies keep positions open on the website even though they have a hiring freeze. It’s a image thing. Some even go through the song and dance of interviewing people (locally that requires no cost), only to not hire.”
Very true, I interviewed several times over the years at Oracle Corporation. Qualified for the open DBA jobs. Every time did well on the interviews and background check. Then hiring freeze emails and phone calls from the manager and recruiter. Very frustrating to spend hours and get hopes up for a job prospect only to have it turn to dirt.
