A long winded HR screening (1-1.5h), then a technical round 2-2.5h and after that a Manager Interview. Salary ranges for IC4-IC5 were very low, 20-30% lower than other similar companies at this time.
The questions revolved mostly around very basic Java Core and Spring Core stuff and some old design patterns, literally a sloppy selection of the classic "top 100 Java Interview Questions". Despite this being Principal/Architect role, I received almost no questions around Software Architecture, and absolutely no System Design questions. It felt like a simple Senior dev interview from 2010, with sloppy interviewers who have no idea what they are looking for and spent 0 time coming up with meaningful questions. A well prepared medior or senior dev could have passed the interview easily.
Behavioural questions revolved mostly around fighting and convincing your own managers, some of these were poorly explained and I felt that they were looking for a particular response, not typical negotiation/conflict resolution.
