Frustrating experiences in the current job market.

I am pretty much bright in studies atleast from B school and started my career with a bang in one of the top manufacturing company with good ctc. For context I worked in sales and marketing dept. This went on for 2 yrs and I was dissatisfied for most part as I was given a responsibility that is very hard to produce results and the market situation was so bad. Eventually, I quit to support my dad in his native and decided to take up a job after some much needed break. So, here is the thing. I feel so unlucky and the selection process is downright frustrating in an already tough market. Example 1: Was contacted by a top fintech firm after seeing my profile. Cleared total of 5 rigourous rounds stretched over 2 months. Finally they informed that my experience did not fit their requirements. I was like wtf. why did you not see in the beginning itself?? I wasted my time and energy over this. Example 2: This is another fast growing on demand delivery startup which went for an IPO last yr. They contacted me again with good ctc and a dream location. Everything was fast and again I cleared all rounds in 2 weeks. They informed I am selected and then asusual they ghosted for sometime. Again a week back they asked few documents and assured to release offer in somedays. 3 days back the HR informed that due to structural changes the role has been removed. I was devastated. Its so hard to come to terms with this. Even after working hard with stellar profile, work ex and good interviews, I am not getting through due to things not in my hand and the above two are just few examples and I have been facing zero feedback and ghosting by many companies after few rounds. Is this how it is or I m unlucky or I need to do it much better in any areas?
