Questions & Answers about mensetsu ni wa, jimina fuku ga ii to omoimasu.
には is に + は.
- に marks the context or occasion: for / at an interview
- は adds a topic or contrast nuance
So 面接には means something like:
- when it comes to interviews
- for interviews
- as for interviews
The は can make the statement sound a little more like general advice or a rule of thumb. It can also suggest contrast, as in: maybe different clothes are fine in other situations, but for interviews, plain clothes are best.
Yes, 面接では is also possible, but it is a little different.
- 面接には focuses more on for an interview as a purpose/situation
- 面接では focuses more on in the setting of an interview
In many everyday cases, both can work. Here, 面接には sounds very natural for giving advice about what is appropriate for interviews.
