My experience has been: 1- redirect to another engineer. 2- keep track of the convo. If it is going off the rails help the engineer get back on the rails 3- if the engineer cannot help, jump on a call and explain to the engineer how to help. Then let them help. This is how teams grow. This also let's you, the technical leader, inject yourself and assist the team without being the only source of truth. And also you become trusted. Win. Win. Win.
