Data Structure and Algorithms are indeed mandatory things in almost every tech interview. Whether it be Google, Microsoft, Amazon, or any other big tech player – they all ask various questions based on Data Structure and Algorithms during their recruitment process.
And you’re not required to have a decent knowledge of Data Structures and Algorithms just because of solving several coding problems but apart from your programming or technical skills – it allows the interviewer to assess your problem-solving skills and how optimal and efficient solution you can provide for a particular problem.
However, some of the individuals often treat DS and Algorithms like other computer science subjects and even tend to ignore them as well. Though there may be many reasons behind it such as – lack of guidance & mentorship, unavailability of quality learning resources, etc.
But neveropen has resolved this major problem of all the individuals as we’re providing you with the DSA Live for Working Professionals course where you’ll get to learn all the Data Structures and Algorithms concepts to crack the interview of your dream company! As the name suggests, the course would be very much beneficial for the working professionals as the classes will be scheduled for Weekends – Saturday & Sunday.
Course Details
It will be an interview centric extensive online (live) program to build and enhance your DSA skills. The course is designed in such a manner that it will help you to improve your problem-solving and coding skills by enhancing your understanding of Data Structures & Algorithms. The primary goal of this course is to help you in the preparation for the Coding interviews of companies like Amazon, Microsoft, Uber, etc.
As it will be an online live class – you can attend this class from any geographical location and can ask your doubts or queries as well to the instructor similar to an offline classroom program. Though the course is open for everyone who wants to learn Data Structures and Algorithms, it is majorly recommended to Pre-Final / Final year students preparing for the Placement drives and Employees looking for a job change.
