Columbia's 3-2 combined plan engineering

My son is considering this 3-2 engineering program.
Does anyone have first of second hand information about this program? We’ve already read all the pages on Columbia’s website that pertain to the program. Therefore, only interested in hearing from students in the program, relatives or close friends of those students, corporate recruiters or those familiar with recruiting perspectives, anyone else with first hand knowledge.
How well managed?
Success rate - graduation rate?
Student rating?
Difficulty?
Outcomes?
Etc.

Edit:
Focus is chemical / materials engineering

If he meets all the requirements, he is definitely getting in. I am in 3-2. Graduation rate is normal, if you work hard.

I know this is not what you are asking for, but you should also consider Haverford’s 4/1 program. After 5 years you end up with a Bachelors from Haverford and a MASTERS in engineering from Penn.

My son’s plans have changed.
