Past performance does not guarantee future results.

That being said, I would put an emphasis on company culture and company stability over seniority. Seniority is a wonderful thing but going to work in an adversarial environment is no fun at all.

Make the best choice based on information available today, that’s the best you can do. There is no crystal ball. And over time, resist the temptation to keep track of where you would have been had you chosen the other company.

Best of luck!
