I am with (Cite Contribution) & Ankita Shah in believing that one learns ONLY by asking or enquiring. There's no other way out for anyone, including myself. And in fact, the BEST time for learning by enquiring IS NOW, especially when you are still early in your career. Once you gain experience, typical human psychology tends to impose limitations on people in terms of being open to learning, due to a sort of 'what will they think of me' syndrome or mentality.
Understanding Indian and Foreign CTCs
Now, regarding your question about Indian and Foreign CTCs, please note that the concept or practice of "CTC" is prevalent in very few countries, including India. Most countries follow a different salary concept—focusing on 'What's my In-hand?'. Apart from the factors mentioned by other members such as exchange rates, cultural differences, etc., the general human psychology in those countries is more focused on the present rather than the future (which is one reason why families in the West may face financial difficulties during recession periods).
For example, in the USA, if an employee is hired at US$40K per annum, in addition to the salary, the legal practice is to include the 401k Plan amount in the employee's salary, with the employer matching that amount—similar to PF in India (for retirement planning and emergencies). Additionally, most employers provide medical insurance payouts. However, when asked about a person's salary, the figure given is usually 40K per annum, with the other benefits being 'taken for granted'.
In summary, this would be the essence of the answer to your question. I hope this information is helpful.
