Tecblic interview questions

Interview Process 2 technical round, 1 CEO round and then last HR round. I have clear the round and CEO is surety that you have to selected come to office on next day to discussed 10 min HR round but the HR is not called and when i followup they have just saying project is coming but there is some budget is not finalized so mail me you are not selected. So if you are not final then why are you west of time to candidate. Fake commitment. no answers with 2 weeks up. and showing positive but last round it just fake commitment

It has 3 rounds including 2 technical and 1 Hr round . I gave all the round and i was pretty sure that i will get an offer but i don't know what happened , finally i rejected in HR round .
