I have been working on a remote job for some time now. I am now going for apply for office jobs. The question I am now asking myself do I actually know algorithms and data structure? How do I make sure I am ready for an interview?

Reading articles like this :slight_smile:

There are tons of articles on preparing interviews out there. I would search for them.

Thank for reply will check the link but I have been googling the same for hours and ended up getting more n more confused. What I got till now is I have assess myself by participating on hackerrank etc. And implement and practice common algorithms and compare time/space complexities with the common accepted ones.
