Phone Screen: Based on previous projects and resume. Coding question: Design counter. difficulty level: easy Panel interview: interview 1: coding : Palindrome with Vowels (easy) interview2: performance: interview was mostly Release engineer and instead of anything to do with perf. this was mostly deployment related round. interview3: performance: Interviewer explained their domain expertise and kept asking question in-their domain vs. candidates' expertise domain interview4: Hiring manager: spent good 35 min explaining org tree, business structure. No question on resume, behavioral etc. No indication on what roles and responsibilities would look like. Also mentioned, if all feedback was positive- I'd need to do two more rounds (after 7 rounds). In their words, i was't told this one before because they didn't know how the interviews would go. interview5: performance: simple instance trouble shooting questions+ coding : arrange character by frequencies (easy). both interviewers were New grads/hires. interview6: QA: coding question but interview was struggling with C++ syntax. interview
