Do NOT accept it as admission of incorrectness. That will typically create an image that you're not a good worker, even when you're just trying to be polite to the person giving feedback.
Here's the pattern that I've found useful:
1/ Rephrase the feedback "What I heard you say...". This buys you a bit of time and putting feedback in your words takes the personal sting out
2/ Turn it into a non-hostile discovery discussion by saying something like "I'm interested in understanding why you think x, y, z...". Layer in any relevant context in your question phrasing... e.g. if the feedback is contradicting the project objectives then you may want to add that in your question
3/ Rephrase what you heard in your own words
4/ Repeat steps 2-3 until you have sufficient clarity
5/ Decide the appropriate next steps and articulate that. A feasible next step might be to take no action because you either resolved the issue through discussion or identified it's not a priority
100% Agree. My first startup job, I learned a ton but the second one was pointless. Target strartups with superstars - those who have a track record of winning. It makes a difference.
I've had similar issues. Tried delivery services for first time recently through Chipotle with ETA of 15-20min. Doordash was fulfilling the order, which showed up after 1 hr. By the way, the Chipotle was 3 min drive from my place. Since then I've been picking food myself.
Not sure I understand the product positioning
