10 Powerful Job Search Hacks Every Tech Fresher Must Know

Breaking into India’s competitive tech job market can be challenging for freshers. Companies like TCS, Infosys, Wipro, and HCL receive thousands of applications for every role. But with the right strategies, you can stand out and land your first IT job faster.

Here are 10 proven job search hacks every tech fresher should follow.

1. Build a Strong LinkedIn Profile

LinkedIn is a goldmine for tech job seekers in India. Recruiters from companies like TCS, Infosys, and Wipro actively scout profiles. Optimize your LinkedIn by:

• Using a professional photo and a keyword-rich headline (e.g., “Aspiring Full-Stack Developer | Skilled in Python, JavaScript”).
• Writing a compelling summary showcasing your skills, projects, and career goals.
• Adding certifications from platforms like Coursera, NPTEL, or Udemy.
• Connecting with recruiters and joining groups like “Tech Jobs India” for networking.

2. Tailor Your Resume for Each Job

A generic resume won’t cut it in India’s tech job market. Customize your resume for each role by:

• Highlighting relevant skills (e.g., Java, Python, or cloud computing) mentioned in the job description.
• Including measurable achievements, like “Developed a web app with 95% uptime during college project.”
• Keeping it concise (1 page for freshers) and ATS-friendly with keywords like “software engineer,” “data analyst,” or “DevOps.”
• Using tools like Jobscan to align your resume with job descriptions.

3. Master Coding Platforms

In India, tech companies like HCL, Accenture, and startups heavily rely on coding tests. Platforms to focus on:

• HackerRank: Practice data structures and algorithms.
• LeetCode: Solve problems asked in FAANG and Indian tech giants.
• GeeksforGeeks: Study company-specific questions and interview experiences.

Dedicate 2–3 hours daily to coding challenges to ace technical rounds.

4. Optimize Your Resume for ATS

Most companies use Applicant Tracking Systems (ATS) to filter resumes before they even reach a recruiter. Use relevant keywords from the job description, keep formatting simple, and highlight technical skills like programming languages, frameworks, or tools you know.

5. Network Like a Pro

Connections often open doors faster than applications. Join tech meetups, hackathons, coding bootcamps, and online communities. Reach out to industry professionals on LinkedIn with a short, personalized message.

6. Leverage Referrals

70% of jobs in India are filled via referrals. Ask:

• College alumni working in tech
• LinkedIn connections
• Friends & family in the industry

7. Apply on Niche Job Portals

Instead of just Naukri & Indeed, try:

• AngelList: Startup jobs
• CutShort: Tech-focused roles
• Hirist: IT & Developer jobs
• Instahyre: Curated tech opportunities

8. Prepare for Behavioral Interviews

Tech interviews aren’t just about coding. Expect questions like:

• “Tell me about yourself.”
• “Describe a challenging project.”
• “How do you handle failures?”

Use the STAR method (Situation, Task, Action, Result) for structured answers.

9. Prepare for Aptitude and Technical Interviews

Indian tech companies often start with aptitude tests followed by technical interviews. To excel:

• Practice quantitative aptitude, logical reasoning, and verbal ability on IndiaBIX or AMCAT.
• Brush up on core subjects like DBMS, OS, and Computer Networks using GeeksforGeeks.
• Be ready for coding questions (e.g., reverse a linked list) and system design basics for higher-tier companies.
• Mock interviews on platforms like InterviewBit can boost confidence.

10. Attend Hackathons & Coding Contests

Winning (or even participating) in hackathons can:

• Get you noticed by recruiters
• Add real-world problem-solving experience
• Win prizes & job offers

Check Devfolio, HackerEarth, and CodeGladiators for upcoming events.

Final Thoughts

Your first tech job is about strategy, preparation, and visibility—not just sending resumes. By applying these 10 hacks, you’ll boost your chances of getting noticed and landing interviews faster.

Stay consistent, keep learning, and remember—every application is one step closer to success.

C interview questions

C interview questions

C interview question1: What is C language?

Answer: The C programming language is a standardized programming language developed in the early 1970s by Ken Thompson and Dennis Ritchie for use on the UNIX operating system. It has since spread to many other operating systems, and is one of the most widely used programming languages. C is prized for its efficiency, and is the most popular programming language for writing system software, though it is also used for writing applications.

C interview question2: Inprintf() Function What is the output of printf("%d")?

Answer:1. When we write printf("%d",x); this means compiler will print the value of x. But as here, there is nothing after �%d� so compiler will show in output window garbage value.

2. When we use %d the compiler internally uses it to access the argument in the stack (argument stack). Ideally compiler determines the offset of the data variable depending on the format specification string. Now when we write printf("%d",a) then compiler first accesses the top most element in the argument stack of the printf which is %d and depending on the format string it calculated to offset to the actual data variable in the memory which is to be printed. Now when only %d will be present in the printf then compiler will calculate the correct offset (which will be the offset to access the integer variable) but as the actual data object is to be printed is not present at that memory location so it will print what ever will be the contents of that memory location.

3. Some compilers check the format string and will generate an error without the proper number and type of arguments for things like printf(...) and scanf(...).

C interview question3:malloc() Function- What is the difference between "calloc(...)" and "malloc(...)"?

Answer:1. calloc(...) allocates a block of memory for an array of elements of a certain size. By default the block is initialized to 0. The total number of memory allocated will be (number_of_elements * size).

malloc(...) takes in only a single argument which is the memory required in bytes. malloc(...) allocated bytes of memory and not blocks of memory like calloc(...).

2.malloc(...) allocates memory blocks and returns a void pointer to the allocated space, or NULL if there is insufficient memory available.

           calloc(...) allocates an array in memory with elements initialized to 0 and returns a pointer to the allocated space. calloc(...) calls malloc(...) in order to use the C++ _set_new_mode function to set the new handler mode.

C interview question4: In printf() Function- What is the difference between "printf(...)" and "sprintf(...)"?

Answer: sprintf(...) writes data to the character array whereas printf(...) writes data to the standard output device.

C interview question5:Compilation How to reduce a final size of executable?

Answers:Size of the final executable can be reduced using dynamic linking for libraries.

C interview question6:Linked Lists -- Can you tell me how to check whether a linked list is circular?

Answers:Create two pointers, and set both to the start of the list. Update each as follows:

while (pointer1) {

pointer1 = pointer1->next;

pointer2 = pointer2->next;

if (pointer2) pointer2=pointer2->next;

if (pointer1 == pointer2) {

print ("circular");

}

}

If a list is circular, at some point pointer2 will wrap around and be either at the item just before pointer1, or the item before that. Either way, its either 1 or 2 jumps until they meet.

C interview question7:string Processing --- Write out a function that prints out all the permutations of a string. For example, abc would give you abc, acb, bac, bca, cab, cba.

Answers:void PrintPermu (char *sBegin, char* sRest) {

int iLoop;

char cTmp;

char cFLetter[1];

char *sNewBegin;

char *sCur;

int iLen;

static int iCount;

iLen = strlen(sRest);

if (iLen == 2) {

iCount++;

printf("%d: %s%s\n",iCount,sBegin,sRest);

iCount++;

printf("%d: %s%c%c\n",iCount,sBegin,sRest[1],sRest[0]);

return;

} else if (iLen == 1) {

iCount++;

printf("%d: %s%s\n", iCount, sBegin, sRest);

return;

} else {

// swap the first character of sRest with each of

// the remaining chars recursively call debug print

sCur = (char*)malloc(iLen);

sNewBegin = (char*)malloc(iLen);

for (iLoop = 0; iLoop <>

strcpy(sCur, sRest);

strcpy(sNewBegin, sBegin);

cTmp = sCur[iLoop];

sCur[iLoop] = sCur[0];

sCur[0] = cTmp;

sprintf(cFLetter, "%c", sCur[0]);

strcat(sNewBegin, cFLetter);

debugprint(sNewBegin, sCur+1);

}

}

}

void main() {

char s[255];

char sIn[255];

printf("\nEnter a string:");

scanf("%s%*c",sIn);

memset(s,0,255);

PrintPermu(s, sIn);

}
