I interviewed last week. The flyforfood gouge is spot on. The tech interview was some questions on jepp enroute chart (pointed out mea, maa, diff between blue/green, cop, comp reporting point, etc) , 3-2-1 rule of thumb for planning descent, when is alt reqd, what is fuel req't for ifr, decode a metar, given dfw airport diagram (what is displaced threshold, runway remaining, etc) and asked if we can t/o and if so was a t/o alternate needed based on that weather (was good rvr but 100 ovc) so no alternate reqd, how long to report change of addy, how long temp cert good for.
HR interview was straight forward. Talked about anything on your app that need addtl info (ie checkride failures, etc), why eagle, why should we hire you, describe yourself in one word, what makes a prof pilot, what trait would you change about yourself, etc.
There was alot of people interviewing that day so the interviews were kept brief. I do think personality plays a lot into getting hired too, not just knowledge. Try to get along with everyone. Everyone you meet during the interview process is an Eagle pilot (Cap or FO).
