Is there any long career in IT industry

Hi All, I am working as a sde since 6 months. Recently I saw layoff from paytm. So i am in doubt that after a so many hard work in one day company will do layoff and it may be happens that layoff people didn't get the job. At this time people will totally depressed. I want to ask whether majority of layoff people got the job again or not. Suggest is there any long career in this IT industry.
