Campus Recruitment – Resume Preparation – Sample Resume Format

Sample Resume Format

1. Personal Details: Your name, address, telephone number(s) and email address.
2. Career Summary: Replace your “Objective” with a “Career Summary”. A Career Summary is designed to give a brief overview of who you are and what you do. Most Objectives sound similar: Seeking a challenging, interesting position /maximizing the bottom line with my contribution/ To be the best in industry etc. Develop a summary that highlights your technical skills and how you have used them before. Writing long objectives diverts the attention of a hiring manager from the real purpose. Do not write any irrelevant or negative information (Gap in your education, backlogs, low percentage, employment gaps, change of career, personal experiences, etc.).
3. Education and Training: A list of your formal academic qualifications, certifications and any other relevant training you have completed in reverse chronological order, putting the most recent education first. Write achievements instead of responsibilities. Begin accomplishment statements with powerful action verbs.
   Certifications are done to learn technical skills which are in popular demand. List the certifications done under separate heading. List the full name of the certification, the issuing organization or institution and its location and the date issued.
4. Skills: This is the place to put important and/or interesting information that does not fit anywhere else. With the advancement of technology, it is increasingly important to include a section on computer skills. This should include your knowledge of computer programs, hardware, software, database knowledge, and/or Internet functions. If you have any other notable skills, such as foreign languages, artistic accomplishments (like passing diploma in music/arts), or writing skills, include these here.
5. Project Details: Write only the most important information in this section. Following details would be sufficient.
   Project Name.
   Short description of project (Not more than 5 to 6 lines).
   Your role in project (This is very important).
   Technologies used in project.
   What you have learned or achieved during the project.
   Any recognition to project like awards, certificates, letter of appreciation, honors conferred, etc.
   Don’t write everything about your projects. Example, How you started, who were the members of your team, how many lines of code you wrote etc. That will make the resume very lengthy.
6. References: Simply indicate that references are “available upon request” in a paper version of your resume. You should know at least 3 people who can serve as your references. Ask in advance for permission to use them as references. Use faculty and employers as references, not personal acquaintances. Do not include their names, address, or phone numbers on the resume. You may send a separate sheet with this information along with your resume, or wait until the employer requests references.

Contents of a Good Resume

Contents of A Good Resume

•  Personal Details: The most important detail is your name, mentioned in bold. Your contact information including email IDs and telephone numbers should be clearly written.
• Summary: Writing an objective is a thing of the past. Instead, summarize your experience and skill set in one or two effective sentences. This would immediately grab the hiring manager’s attention. E.g. Five years of experience in software quality assurance.
• Past Work Experience: Include the details of your previous employment and briefly mention the significant projects that you were involved in. Mention the organization name and also the duration of your work. The order should be starting from recent to past.
• Educational Qualifications/ Training:
  Mention the formal qualifications, certifications and training that is relevant to the position being applied to.
• Core Competencies: Mention your skill set or core competencies. This section would enable a hiring manager to decide whether you are suited for the job or not.
• Professional Achievements: Write a few sentences about your noteworthy professional achievements. Try to include testimonials in support of the same, along with the resume.
  Example: getting funding for your college project which was recognized as a viable and a good project by the funding company/ Winning a technical white paper competition etc.
• Co-curricular Activities: This section does not mean you write about your hobbies. Write about your activities in areas other than academics or professional life, which have contributed to your overall development. Example: membership and participation in cultural groups/ sports/ social service etc.
• Personal Interests (Optional): Some personal interests like writing articles, poetry, reading foreign languages that add to your competencies can be mentioned.
• References: You may mention a maximum of three references who could either be your academic faculty or your previous employers. Friends , neighbors or family cannot be used for reference. Indicate that references are available on request. In case your hiring manager needs more information, send the name, contact number and email ID as a separate attachment. Writing a resume requires your patience and time. Devote a good amount of time in resume development, thereby increasing your chances of being chosen for a job interview.

Campus Recruitment – Resume Preparation – Tips to build an effective Resume

Tips to build an effective Resume

Your resume is the most important document that the employer would refer to. Hence, it is very important to keep your resume professional and up to date. Include your professional details, academic details total work experience, skills, tools and programming languages known. Do not lie about your skills and experience. Resume should be written honestly and carefully. Do not prepare a very long resume. A short but to the point resume should be prepared. Do not copy the resume from other sources. Write it on your own although you may take reference from sample resumes.

Tips to build an effective resume

• Choose a good resume format.
  Pick up a font that is easy to read. Fonts such as Verdana, Times New Roman and Arial in sizes 10-12 are conducive for reading.
• Use the right keywords in your resume.
• Use effective titles.
  Example:
  Bad title: Software development.
  Good title: Developing Java API.
•  Divide your resume into sub sections.
  Example: One section for details about your work experience, the second section about your academic qualifications, the third about your skill set, the fourth about your personal profile etc.
• The most important points should be placed at the beginning of your resume. This should be uniformly followed in the individual sections as well. The most recent work experience will come first.
• Your contact details including your address telephone number and email ID should be clearly mentioned in the resume.
• Use bullet points and short sentences in your resume. Do not make the resume boring by giving in depth explanation or being repetitive.
• Avoid writing negative sentences.
• Write a few sentences about your professional goals.
• Use your testimonial references for any skill that you would like to highlight.
  Example: winning a technical white paper competition at the national level (testimonials included).
• Do not include your age, unless it is specifically asked for.
• Do not create a standard resume for all the jobs to be applied to. Restructure your resume depending on the job for which you are applying.
• Do a spelling and a grammar check before you send your resume.
• Update your resume on a periodic basis.
• Mention dates in order.
• Do not forget the basics, like your name.
• Mention the employers for whom you have worked.
• Mention the companies for whom you have interned (done your projects).
• Do not use heavy vocabulary or too much of jargon(technical words).
•  Get your resume reviewed by a professional.

• Lying about past work experience or qualification.
• Committing spelling and grammatical errors.
• Making the resume colorful in appearance.
