Like I said, a good interviewer ensures you understand the solutions of those problems (the problem might even be formulated in a different form than the exact form you learned) not just typing out text verbatim. If you do understand the solutions of top 100 coding questions, I think you have a good start. Part of solving the problem in an interview will also be being able to code, so it's also testing your coding ability in a given programming language. True that software engineering is more than that, but those other things largely depend on in-house company processes, tools and policies so you would learn them afterwards.
