Lots of help on this forum, lots of TLs, Assistants, Experienced TMs, etc. All happy to help!!
Interview is pretty straight forward! Management is 3 parts, regular positions are 2 part. Questions are situational like "Tell me about a time when you..." Unfortunately we cannot share the actual interview questions due to Spot's lawyers not being friendly to this site. <shrug>
I am assuming that you have previous work experience? So use it to your advantage; good and bad. Just be ready to answer questions about time pressure, co-workers, teamwork, difficult tasks, etc. and be ready to talk about how you handled the situation and what you learned, what you would do differently in the future.
If you have any specific questions please post them, otherwise check out other threads. Try under "Team Lead and Executive Team Lead" Forum.
Interview for TL tips questions
(probably best thread as most others apply to current TMs attempting to move up)
