Our current team leader is quitting his job (starting his own company) and thus we are searching for a new team leader. It's a small team of 4 people (Team leader included). Since it's a small team we expect the team leader not to only manage us but also do some coding.
Because of this I convinced the R&D manager to let me join the interview so that I can evaluate his technical skills and managing skills, and have some say on behalf of the team.
I have little experience interviewing people let alone my future Team leader. What I search in a team leader is someone who isn't running a dictatorship but someone that when there are issues there is a discussion about it and we take everyone on the same line.
How can I best go about soliciting information in these and other key areas? Are there glaring omissions from this short list of key qualifications that I should focus on, given my position on the interview team?
