I've been at my new job for about 5 months. My manager often insinuates I'm lost in the company by saying things like "if you remember from the OKRs" whenever I ask a question in our meetings.
There are also other ways he communicates with me that insinuates this and about me towards other people like "she may not want to do that" , instead of "I'll see if my team has the time and capacity to take this on." The way he communicates paints me in a bad light to other people.
I was hired by the CEO for this role, though he hasn't bothered to do a 1:1 with me since I've started. I also see other employees getting their 30/60/90 day check ins. I never received any.
I've begun to hate coming into work every day. The only thing that gets me by is the love I have for the technology (I'm in computer vision), and being around engineers I am learning from.
I have another offer lined up with a hiring + direct manager who is great with me. The role is also a step up "Lead Developer Advocate" with a pay increase of about 40k.
1. Should I be concerned about how a 5 month job looks on my CV?
2. Should I be concerned about this company black labeling me to people in our network for leaving so soon? (It is a YC company)
3. What would you do in my shoes?
