Accenture Sr. Software Engineer interview questions

The interview process is extremely weird and complete rubbish. The interview was of 3 stages 1. Stage 1 coding round (No technical questions asked) 2. Stage 2 coding round (No technical questions asked) 3. Stage 3, a 3 hr round interview with two interviewers and again 2 coding rounds in that and hardly a technical question. + you do a presentation No questions asked on design, no algorithm-based question, no questions on performance tuning, no questions on frameworks. This is extremely weird just coding round and that too some concurrency which you solve through with basic constructs like synchronized, wait and notify. In the last coding round, this developer asks you to write a lexer with too many if's and but's, because he might have encountered it in the production and he expects you to write it down in 1 hr and has a serious communication problem. His question also took me by surprise. Eventually, in the rejection, they cited coding issues, and I am wondering how did they approve the first two rounds of my coding. No HR rounds nothing and 3rd stage is the final one. It's an extremely unbalanced interview process.
