Whiteboard coding so a test of software engineers and is a part of the technical interview that is done prior to allotment of a job position. You will not have the usual aids like the hotkeys and the code editor and will be require to solve the algorithms and data structures during the test. Anyone can get a bit nervous and you may also fail if you have not well prepared for the interview and the whiteboard test. Below are the most common errors an mistakes that are done by the interviewees. Read the article to avoid them during your interview and test.
Being unaware of the algorithms and the complicated data structures
If you say that you do not have any idea about the working of the Big O notation, you cannot clear the test. It shows that you do not understand the algorithms or have inadequate knowledge. You can prepare for the whiteboard test better by studying the data structures. It is a important part of the computer science course. Read more about the weaknesses and strengths and try cover to cover all aspects.
Pretending to beat knowledge that you actually do not
The interviewer may use technical jargons and languages that only the well-read ones could interpret. For instance, he may point out something like “… so now we are at the post order traversal”. You may pretend that you know what he means when you actually do not. You may answer “yes”, but later when the question comes up again, you are at loss of words!
Being dishonest will not help you towards your selection nor does it shows your personality in a good and positive light. It is better to ask for more details, when you do not know about something.
Writing the code while being unaware of its effect
You may start writing the code while not knowing what will it do. You may add the loops, subroutines and prepare a poorly baked and messy code that is all over the whiteboard but has no meaning or worth.
It is hence better to brainstorm the problem at hand completely before starting on the actual code think about a few ideas after taking along deep breath. You can also do some samples and draw pictures to find a potent solution. Ill-written and wrong codes will yield to you no marks, so do not waste any time with them.
These, along with errors with debugging, are the common mistakes done by applicants during a whiteboard interview. Do your practice by solving the problems and be prepared for anything.HNR Tech, the leading digital services company brings to you a world of informational and knowledge and offers world class services to make you excel in your business and professional life.
