There is some great advice in this thread. One thing that I've learned is that different organizations have very different cultures and ways of viewing technology (and thus technology leadership).
Some are more deadline oriented, some are more bug/problem oriented, and some are more product oriented, and others care a lot about the price per head of engineers and would prefer to outsource everything to the third world if they could ever manage it. A small number of companies care about open source contribution, attracting top talent, and innovating.
So whoever is hiring you probably has a very clear idea of what they want from the tech lead, so considering that the goals can be very different, you might want to ask this question. In my opinion, it won't seem like a naive question to ask because there are so many facets to people and technology leadership.
