I am a electronic engineer.Now I am pursuing my MBA in marketing(distance).I had 2 years of exp in telecommunication infrastructure(electrical) as site engg(electrical) with gross salary of 12k/month.Now I have recently changed to Business Development Executive in electronic sales of 10k/month, 3 months back since my background is E&C.Now I have an offer in telecommunication as project coordinator(civil&electrical) with gross salary of 25k.Is it wise to shift my career into telecommunication back again? But I think marketing has good scope and later I can earn the money once I have experience.Please suggest ASAP since the offer last this week only and I am in a confusion whether to see a new career or Salary as we are middle class family.
