I am in very larger company HR (about 85,000 employees and 15,000 contractors).
Good, you switch company get higher pay.
Bad, you switch too soon.
The statistics shows, average American switch job in 3 years. Your job history that your personal DNA. Future company may not hire you because you will not stable with a company. If I read your resume, I will not hire you for this reason.
As I said, 50%/50%, you balance good for your 1.5 years, you narrow your future....
