IBM Software Engineer interview questions

My experience started in August with a trip to my University's career fair. After discussing my resume, shaking hands, talking about my interests, etc. I was handed multiple individuals business cards and told to apply online for a couple different positions as well as take their aptitude test online (the one with the math and other items). I applied online to 3 (maybe 4 - I can't remember since it was a while ago) positions and about a week later, got the "Thanks but no thanks" declination email for all of my applications. So, I looked into other companies and accepted an offer. Fast forward a couple weeks: I get a call from a representative at IBM saying that I was going to be extended an offer and that details had already been sent to me (I checked my email while on the phone and there they were). I asked if they had the right person and they responded with my name. I was surprised to say the least and explained to them how I was told to try again next year a couple weeks ago and ask why I was being approached now. They said that after looking over my application, they thought I would be a great fit. I declined on the spot over the phone because I had already accepted an offer a week earlier. There were no interviews (save for my conversation at the career fair), no questions other than the aptitude test, just an offer out of the blue.

For freshers they hire from campus generally tier1-2 colleges like NIT,IIITs For experience teamlead will take your interview and 1-2 team members also
