Few companies don't provide timely feedback, no proper scheduling and total time waste.

Points to remember.

1. Ask recruiter for SLA of each round in the beginning of interview process.
2. Try to get a feedback or do a self analysis. 2 weeks is the maximum time for any feedback.
3. Don't chase recruiters, it's better to try for other companies. You will get a better offer.
4. If recruiter is changing the job position/title in the end. Downgrading like SDE-2 to SDE-1 role,
   don't join that company, these are the dirty tricks.
5. Don't go for big company names, choose wisely between product/fintech/startup/service-based.
6. Don't get upset, there are so many companies. Your hard work will get you a dream job.
7. Don't limit yourself.

I don't want to add companies name here.
