Inconvénients
Very bad work-life balance. Lots of work on weekends, until late without a single penny or recognition. You need to sell your soul to Schlumberger and forget your family. No Christmas, birthdays, Sundays, etc… If you have a manager that does not like you then your life will be a hell and you will have a bad appraisal that will impact the rest of your career. You just follow receipts in the first three years. High turnover. Around 50% of new hired do not reach 3 years in the company. No respect from the senior staff in basic human necessities: vacations, days off, etc. Sometimes a simple thank you is difficult to hear. Lower salaries compared with competition and clients.
