Way to survive in industry

1. Never compromise on ds/algo practice and design. You should get time every week for this.
2. Never trust any company and don't settle
3. Company can replace you anytime. HR just need to float job and hundreds of applicant will apply whereas if you need to find a job you first have to grind LC and design and then you will get ready. This makes a uneven situation.
4. You are not replaceable for your family, friends and loved ones

Benefits of working in toxic or too much work environment

1. Learning
2. A little better payscale
3. Close peer group of colleague

Cons

1. You won't get time for practice your interview skills so you would have hard time cracking interviews
2. High pressure can leads to high stress that can lead to less growth in long run and burn out. Once you burn out, your Employer attitude may change
3. You would not have time for your friends and family. You may even lose your social circle. Whereas the colleague group that you would form would start to fade away once you leave that place.
4. It would form a unbalanced relationship where you are more dependent on your Employer and won't be able to do much even if you get less increment or other issues
5. You would not have time for investment or growing your wealth. Your long term wealth is not how much you earn it is how much you have(savings + growth on saving)
