Pair the candidate with an interviewing engineer, give them an hour or two to solve a problem as a team. The interviewer isn't an adversary; their job is to assist the candidate like they would if they were working on a real problem. Repeat this process if necessary. Get everyone together and talk about past projects the candidate has worked on. Have the interviewers evaluate the candidate, and make your decision. You know whether the candidate can code, and you've removed the adversarial nature and unnecessary stress from the interview process. Most importantly, you got to see them work in a much less artificial environment that's closer to what they'll be doing day to day.
