Caterpillar Associate Software Engineer interview questions

Online Test 1 - Aptitude, Logical, Verbal, Computer Technology related MCQs Online Test 2 - Same as Test 1 + 2 Codes (Level - Easy) Group Discussion - On Tech/Politics/Sports/General (Number of candidates halved) Tech+HR Interview 1 (for Services probably) - Resume Probe, focus on Projects: Tech stack (mostly Python based for me), approach , team work, planning. Went well for me, they told me whether I want to develop and be in R&D. I said yes. Tech Interview 2 (for Dev/R&D) - Questions from Skills in Resume. Lot on Java and DBMS. Level - Medium, but I forgot some stuff about Collections.
