WSA Sr iOS Developer interview questions

Only conceptual Theory related questions. No Logical or Problem solving questions. It's a drive kind of F2F interview. Where you will see 20-30 candidates in each tech. Good thing is they will complete process for 1-2 hrs for all candidates and send out. ** I believe, They are doing for Audit or Beneficiary purpose. ** Good thing is you just need to tell I have an interview. All outside staff will respond WSA right from security guards, receptionists, lift man.
