What could be good and reasonable answers for "Why are you leaving your current company?"

I recently found out that a colleague with less experience than me is making noticeably more, and I cannot stop thinking about it before interviews now. It changed the way I look at compensation conversations completely. I used to just feel grateful to get an offer, now I feel like I probably undervalued myself for years. Has anyone else had that moment? Did it change how aggressively you negotiate or interview?

Hey folks -- what’s a subtle interview red flag people should pay more attention to that most candidates ignore at first? I’ll start: - The interviewer constantly interrupts or seems distracted the whole time. - Nobody can clearly explain what the role actually involves day to day. - They dodge questions about turnover, onboarding, or why the role is open. - The interview feels weirdly adversarial for no reason. Anything else that comes to mind?

"If I hand you a single pin, how many uses can you come up with in 60 seconds? Talk me through your thinking as you go. " Yes... this was a real question in one of my interviews! Didn't get the job in the end. I still don't understand the point of this exercise. Why would someone ask this?

This job application process is becoming tiring. It takes approximately 30-40mins to tailor(including editing and formatting) CV and cover letter to each job post. After approximately 4 applications, mental fatigue sets in. I am considering using some form of Agentic AI to scan LinkedIn and apply for matching jobs. A scenario where all I will do in the end is just verify and click submit. Has anyone come across anything like this?
