I recently accepted a job offer in software engineering and my salary is reasonable. I have been working for five weeks, until I was offered a job from a top-tier company with 50% higher salary this week. I had applied and interviewed for these jobs at the same time, but the top-tier company took longer to process my application, or they have had too many applicants.
Although the new job offer is paying 50% higher than what I am receiving at the moment, I am still not sure if I should ask for an excuse and resign from my current job to move on to the new job.
I have two concerns about doing this: (1) The current company has spent some money on my laptop and work gear, and I feel bad if I just leave within a short period of time. (2) The current company has really nice people with whom I have really enjoyed working. I feel bad for moving to a new environment due to a traumatic experience in my first job.
I am not sure if my lack of tendency for leaving my current company is logical, or it stems from my "safe workplace anxiety" in my first experience. That is why I decided to post this question here and ask for opinions from people who are in later stages of their career. Is it a good idea to move on or it is too risky?
