Coding Technical
The interview had two rounds. The first round covered basic questions related to my resume. The second round involved three coding questions, and during that, the interviewer asked questions about the code I wrote. However, the interviewer seemed to lack interviewing skills, focusing on syntax rather than logical questions, making it feel like a memory test instead of an assessment of thinking ability. The feedback also didn't align with what happened in the interview.
