      IS IT RECESSION???
      Many candidates ask me.
      Sir, right now the market is not good. What should I do?
      And 100 times I said that.
      Don't let your fate be decided by circumstances.
      Follow your goals and grow more and more.
      Even if recession or firing is real???
      Are you waiting for your company to fire you?
      Go give some interviews and be ready for any situation.
      Crack the interview and don't accept the offer. Simple without any harm.
      (But the day you will crack the interview, your thinking will change positively)
      But please DON'T GIVE EXCUSES and DON'T SPREAD NEGATIVITY.

      Never, AI can write the programs, but that program will be reviewed, cross checked, tested and deployed by humans only. In future the application development will be very fast. But the number of application creation also be very huge.
