I am here for 7 years now and if you are not with the worst ever company than I recommend you to stay where you are.
The good days of EK are over, until 3 years ago it was great nobody ever left unless he retired, now the company even tries to hide from us how many resign per WEEK.
Some F/O's are stuck here because they are too old to start again at the bottom of the seniority with another company, but forget a quick command in EK, I guess if you join now its at least 8 years.
good luck with your decision
