Introduction
Before we learn about coding preparation for placement, let us take a look at the interviews. Technical interviews are very different from your usual interviews. Students and professionals alike find them daunting, and rightly so. In a technical interview, the interviewer tests your knowledge of subjects along with your problem-solving abilities. It may seem too difficult at first.
But, it can be quite easy to complete your coding preparation for placement if you have a plan and an understanding of what you’re doing. We will give some vital last-minute tips to enhance your coding preparation for placement and increase your chances of bagging the role.
How to complete coding preparation for placement?
You have to be very strategic in your approach when you are going for coding preparations. We have laid out the subjects you must focus on and things you must do as part of your coding preparation for placement.
Let’s start:
Plan
The first thing you should do is plan out your activities properly. You’ll need to study multiple subjects and without proper time management, you wouldn’t be able to study all of them in time.
Preparing a plan would enhance your time management skills, a vital soft skill that recruiters look for in candidates.
First, you should evaluate your current understanding of your coding subjects. It would help you identify your weak and strong areas. Then, you should create a time table and assign time to those subjects according to your grasp over them.
What subjects would you study at this time?
Following are the subjects you should study during your coding preparation for placement:
Technical Problem-solving
The first subject you should focus on is testing your coding skills. It’s the fundamental subject a coder must master.
Most technical interviews start with a programming test. During these tests, the focus is set on judging your ability to write correct code in a limited amount of time.
How should you prepare? You should focus on practising easy and medium-level coding problems at a fast pace. This means you should be well-versed in going through A, B, and C-level problems.
When you are going for a specific company, you can learn what specific programs they run and try to understand their technical makeover. Find out from the previous interview drives what kind of questions were asked by the company. You can conduct coding tests too on CodeStudio.
During your coding preparation for placement, you may need to study multiple programming languages.
If you’re a beginner, it would be best to stick with one or two programming languages. Look at the trends of which programming languages are best suited for the field you are interested in. For example, a survey suggests Python is a top-loved language of many programmers.
Plus, it is a trending topic even in 2021. If you already have knowledge of one programming language, master it and try to learn another to become a more diverse programmer.
You should start with Python if you are new to programming. It has a very simple syntax and has numerous applications. To learn python, you can take our free Python Foundation with Data Structures course. It teaches you the basics of Python and its applications, making you familiar with all of its aspects.
Algorithms and Data structures
After you have practised your programming skills, you should focus on learning about algorithms and data structures. Some vital interview questions on this topic are:
Q: What is a binary search?
Ans: In a binary search, you compare the key with the item present in the array’s middle. If the key is less than the searched item then it would lie in the lower half of the array whereas if it’s greater than the searched item, it would remain in the upper half of the same.
Q: What is a quick-sort algorithm?
Ans: A quick sort algorithm can sort queries or lists quickly. It works according to the principle of partition exchange. Such algorithms occupy less space and divide a list into three parts: the pivot, the elements less than the pivot, and the elements greater than the pivot.
Q: How does algorithm encryption work?
Ans: For encryption, an algorithm uses a string called ‘keys’. The greater the size of a key, the more potential patterns you have for generating cipher text. Encryption algorithms usually employ codes fixed blogs input with length ranging from 64 to 128 bits.
Q: What is a mobile database?
Ans: A mobile database is a database that can connect to a mobile computing device over a wireless network. In such cases, both the client and the server have wireless connections. They allow you to analyse and manipulate data on mobile devices.
Operating System, DBMS, and CN
Operating system, DBMS, and Computer Network are the core of technical interviews. You should focus on the definitions and the application of these technologies during your coding preparation for placement.
Here are some crucial interview questions you should prepare:
Q: What advantages does DBMS offer over conventional file-based systems?
Ans: Database management systems offer various advantages over traditional file-based systems. Following are some of the most prominent ones:
- Reduce data inconsistency and redundancy
- More security
- Make it easier to access data
- Solve integrity problems
- Offer simultaneous access to multiple users
Q: What do you mean by database normalisation?
Ans: Database normalisation is the process of analysing the relation schemas according to their functional dependencies and primary keys. It focuses on minimising the insertion, deletion, and updating anomalies along with redundancy.
Q: What are the different kinds of OS?
Ans: There are five types of OS:
- Real-time OS (For example VRTX, PSOS, etc.)
- Distributed OS (For example LOCUS)
- Time-Sharing OS (For example Multics)
- Multi programmed OS (For example UNIX, Windows, etc.)
- Batched OS (For example Transactions Process, Payroll System, etc.)
Q: Why is an OS important?
Ans: An operating system is a vital component of a computer because it acts as a link between the computer software and the hardware. The OS allows the user to communicate with the hardware and it maintains a balance among the CPU and the same. It also provides the user with a platform to run different programs on.
