If your manager is a good manager, then nothing that comes up in your review should be a surprise. Talk about a plan to get to the next level. Nothing will ever be guaranteed, but if you work together on a plan and have milestones to meet then you’ll have a better chance of getting a raise and promotion. Obviously, not every review cycle can include a raise or promotion, so be reasonable.
A good review has what are called SMART goals. They should be specific, measurable, achievable, relevant, and time-based. If your manager fails to give you goals that meet that criteria, then chances are you aren’t both working toward the same thing. Be open to criticism, because you probably won’t be doing everything well. Make sure you’re having regular one-on-ones with your manager, or whoever gauges your progress. If you’re early in your career, I would recommend every week, or every two weeks at most. This way you have regular feedback. Make sure you take notes.
Depending on what you meant by this question, I’d say Perplexity. It’s got access to a number of different LLMs, and cited its sources. The biggest concern I’ve had when it comes to LLMs is that they eventually make shit up. If you can verify its answers by checking its sources, you have a much higher confidence level in the answer.
