<p>I’m somewhat in the same boat as you since I switched from EECS to Math, then decided I wanted to do data science. Currently I’m thinking I might try to get an analyst-type job instead of the software route (don’t know if that’s the right way to do it).
Anyway I’d agree 61b and then 170 are the best for interviews. I think A and C won’t help you much.
Good luck on getting a job : )</p>
