IBM Software Developer interview questions

Talked to 3 different "recruiters" and they rescheduled my Guide interview 3 times (sometimes HOURS before the interview was supposed to take place). Since I already had an offer from elsewhere, I just canceled the interview after the last time they rescheduled. The recruiter was very unhelpful and unprofessional and wrote with various grammatical and spelling errors, and even got my name incorrect more than once. Overall, a pretty frustrating experience.

Got the interview through employee referral. Was first have a regular recruiter phone interview. The whole process was within 30 mins, very straightforward and friendly. Then I received an online test for numbers and figures. Did not have further interviews tho.
