Northern Trust Analyst interview questions

Probably the worst interview process i've ever had. The Hrs are so hopeless and so unprofessional. on the First day, we had the GD and the APTITUDE TEST which was pretty straight forward. After which they told us to go for lunch and come back. The results were announced and the shortlisted people were asked to stay back and the further rounds would be conducted. after waiitng for nearly 3 hours, one of the coordinators comes and says that the managers aren't free and that we will be contacted in the evening with further details. there was no call for over 10 days, after which we were called for a HR round which was so mismanged and again the same was told that we will be contacted in the evening with further details. now this tops everything i got no call for over 3 months and one day out of the blue they call and ask if you're still interested? i mean what is this? who takes this much time? ABSOLUTELY THE WORST COMPANY ONE CAN APPLY FOR. AVOID IF POSSIBLE
