I am applying for a postdoctoral position in Chemistry (mainly in US and UK universities). I have zeroed on two persons other than my mentor- One is associate prof. and other is an assistant prof. Both have taken my course classes as well as practicals in M.Sc. Both are widely active in their respective research field which aligns with mine.
1) Is it wise to give names of junior faculties? Do the academia look for the repute of the person as well or just they look into the recommendation letter?
2) Does any personal account matter while considering a recommendation or a generic looking letter does fine? I am confused between a professor who was a member of my advisory committee (familiar with me and my work and quite friendly) and another one who is an asst. prof., but is popular for giving excellent recommendation.
