That depends.

I personally believe manager should be hiring their team. If only for the candidate to meet the manager and have a chance to make their decision based on the fit.

But I also was many times asked to stand in for another person. Maybe the manager was very busy and he trusted me I can do good job?

In any case, if you go for a large company and for a long haul it is likely you are going to be changing managers (but still it is good to get to know the first one).

This is one of the problems with a company my friend is at. They do intake without preference to a specific team. They also do re-orgs every 3 to 6 month, so even if they did, the team you interview for might not exist for long anyway. He's on his third team in less than a year. People randomly get moved around due to dysfunction, etc.
