While I'll agree that HR has become a necessity in this day and age to make sure that all the legalities are followed, I'll disagree that they need to be in there doing the actual interviewing. I've had quite a few interviews in the last decade and a half. The good ones never involved HR until the decision was made to hire me.
Example one:
Walked into an FBO that had a Bandeirante parked out back. Walking down the staircase is an old colleague of mine. I say, " hey Gordon, how's it going ? You wouldn't have anything to do with that Bandit back there would you ? " Yes, actually I do, he says. Wouldn't need any pilots for it would you ?. Yes, actually, we have a class starting Monday, can you be here ? ( note, this was on a Friday ). Yes, I can.
See, interviewing doesn't need to be difficult or involve HR.
Example two:
Friend and I walk into Great American Airways office at the Reno airport. Chat with the D.O. about their operation ( we both flew the DC-9 at USAir ). Have a nice chat, tell him we flew the -9 and would be interested in a job if one comes along. Nothing then, but 6 months later I get a call from my friend. He says that GAA is hiring 1 Captain and 2 F.O.s. "I'm one of the F.O.s and you're the other", he says.
Again, interviewing doesn't need to be hard or involve HR.
Example three:
Foreign airline comes to the States looking for 12 American pilots. The " interview " is a sim assesment in the MD-80 sim in Seattle. About 45 minutes of NDB work in 30 knot winds. Take-off, fly a SID with two NDB's in it; hold at an NDB; NDB approach to a go-around; NDB approach to a landing. Afterwards the deputy D.O. says to my friend and I ( same one from example two ). " You come Taiwan ".
Still no HR.
Example four:
Job in Taiwan is about to end so I call some acquaintances at Boeing and ask if they need any pilots. A month later get a call from them saying to come in for an interview. Interview is with the Chief Pilot, a retired Delta MD-11 Captain. We chat about flying in Taiwan and other stuff and then have long discussion on whether or not I'll go back to USAir one day. I promise him I'll stay as long as the assignment they are hiring me for requires. He decides on the spot to hire me and then sends me to HR to get a drug test.
Sum of HR involvement here, sending me to the drug test and processing some paperwork. This at a Fortune 50 company that really need to watch their legalities.
Example five:
North American in 1995. Went to New York and had a chat with the chief pilot and MD-80 fleet chief. Then they took me in to see the owner and we had a short chat. Got hired but turned it down to go to Taiwan, the chief pilot telling me if things didn't work out in Taiwan that I could always give him a call. Very classy outfit.
Again, not an HR person in sight.
So you see, HR really doesn't need to be involved until the decision to hire you has been made. Yea, they may need to brief the interviewers on the things not to ask to keep it legal, but they don't need to be an integral part of the decision process.
