 If you are cutting corners in your code, state that out loud to your interviewer and say what you would do in a non-interview setting (no time constraints). E.g., I would write a regex to parse this string rather than using `split()` which may not cover all cases.

+If you want more structured algorithms practice, I recommend [Educative's Grokking the Coding Interview: Patterns for Coding Questions](https://www.educative.io/courses/grokking-the-coding-interview?aff=x23W) course. This course essentially expands upon the questions here but approaches the practicing from a questions pattern perspective rather than data structures, which is an approach I agree with for learning and getting better at algorithmic problems.

 If you've received an offer (or even better, offers), congratulations! You may heave a huge sigh of relief and think that the toughest parts are over. Well yes, but not entirely! For most people, the reason they're finding a new job is to increase their salary, and salary negotiation is the last stretch in achieving that goal.

The initial offer that you are given is not the best package that the company can offer.

+**Here's something that recruiters don't want you to know -** In most cases, there's room for negotiation on your offer and _recruiters expect candidates to negotiate_. The initial offer that you are given is not the best package that the company can offer. During my last job hunting experience, I received offers from numerous top tech companies like Facebook, Google, Airbnb, Lyft, Dropbox, and I have found this to be true. In most cases, you could always negotiate for more money, and some aspects of your salary is easier to negotiate than others. With many offers in hand, I was able to negotiate a better offer from every company.
 
 If you haven't been negotiating your past offers, or are new to the negotiation game, worry not! There are multiple negotiation services that can help you out. Typically, they'd be well-worth the cost.
