common mistakes made by DBAs when writing CVs/Resumes


On the most common mistakes made by DBAs when writing CVs/Resumes

In DBA on June 8, 2011 at 00:05
Eleanor Roosevelt said: ““People are like tea bags. You find out how strong they are when you put them in hot water.” Same holds for DBAs.
Last week, I read an article in the Wall Street Journal called “Updating a Résumé for 2011″.
It mentions about the top 10 overused terms when writing CVs/Résumés: innovative, dynamic, motivated, extensive experience, results-oriented, proven track record, team player, fast-paced, problem solver, and entrepreneurial.
How true! Having read (or rather scanned as noted in the WSJ) hundreds of DBA resumes over past years, I must say that this is very close to the reality also in the database management world.
But first, what is the difference between a CV (Curriculum Vitae) and a Résumé?About.com and Answers.com say: “The primary differences between a resume and a curriculum vitae (CV) are the length, what is included and what each is used for. A resume is a one or two page summary of your skills, experience and education. While a resume is brief and concise – no more than a page or two, a Curriculum Vitae is a longer (at least two page) and more detailed synopsis.” I see this a bit differently: it is basically the same thing. Americans call it Resume, Europeans call it CV.
Now, what are the most common mistakes made by DBAs when writing CVs/Résumés?
1. Use of cliches: Check your CV if it contains some of the words/phrases listed above. Remove them! We all know that everyone is a team player with proven track record but only one finger hits Enter after typing shutdown immediate.
2. Overbrand yourself: too much information in the CV: No need to explain in several pages what you did for every single project. Nobody has time to read all that. Really! I understand everyone wants to mention about all his skills and knowledge but forget about including technologies you have used for only few weeks or even worst: used for years but mostly on PowerPoint.
3. Including technologies you do not master well: A major mistake is to add to the CV all possible IT software and hardware you can find in Google. I doubt very much the existence of a DBA who can administer all database brands, knows all operating systems, storage vendors and is also a programmer/developer. And here I would point a finger to some employers who demand too much in their job ads.
4. Writing about old stuff: One of the WSJ article’s comments says “The problem with all resumes is that they focus on the past, not on the future”. Absolutely! I always smile when I see in the CV words like Oracle 7, Oracle Parallel Server and Forms/Reports. As if somebody really cares of how well someone masters the Rule Based Optimizer, the proper setting for gc_file_to_locks or when to use the Snap to Grid feature instead of Anchoring.
5. Unbalanced DBA skills: Few years ago, I received a CV where it read “IT skills: Internet Explorer and Oracle”. This is an extreme example but from the CV one should get the idea (for example) if the person is Senior DBA or not. For all I have seen, a typical CV is so unbalanced (see 3. above) that after reading it I am rather perplexed and bewildered of how good the DBA is and what he is most strong at. Two examples: a person is a SQL Tuning expert who has never heard of SQL Profiles or has several years of EM experience but does not the difference between Database Control and Grid Control.
6. Mimic the job ad: Déjà vu, it is so ironic when you see in the CV all you want. The worst case is when people are so lazy that they even copy/paste from my job ad. I reject these candidates at once.
7. Using DBA jargon: The one who reads your CV is not necessarily with DBA background. Too many abbreviations without explanation in brackets might lead to the frustration of the one reading it and ignoring you without cause. Even the word DBA should be avoided and use Database Administrator instead. For many people outside IT the word DBA resembles a profession from a Harry Potter book. Literally!
8. Underestimating the achievements: In the very beginning section of your CV, you want your key skills to shine out at recruiters. Include on the top of the first page what you are best at, your most significant achievements, your top skills. One paragraph! Maximum 5 bullets. That might be your keys success for getting to the interview at least.
9. Photograph in the CV: Do not put a photograph unless the employer/job ad asks for one. You may be judged based on what you wear, your hear style, how you smile. Who knows.
10. Poor Grammar and Spelling: A very recent case: strongest skill was MSSSQL :-)
All of the above is based on my experience and I know that DBA recruitment is often culture based. For example, in the US you cannot ask candidates about age and family status. But in Europe, these things can be at times quite important.
It is worth checking for second opinion. DBApool.com lists the 9 common mistakes in DBA resumes. It is a very good one indeed.
Another article called DBA resumes that make the cut says that “DBAs need to do more than just tell the truth” and the number one tip is “Name the same skills that the job advertisement does”. I am sorry but that is not how you get the DBA job. May be the interview but that is badly wrong advice.
You can google for generic mistakes in CVs. Opinions vary although the tendency is framed.

Oracle Certification E-Magazine December 2012

Oracle Certification E-Magazine
December 2012
Hello Everyone,

The big news in this edition of our Oracle Certification EMagazine is related to a change in the way that exam results are provided at the end of the test (using our CertView tool). This significant process change for the Oracle program sets the stage for tighter integration of candidate information and exam/certifcation results. Additionally, it helps give every certification holder access to important tools available in CertView. The new process was implemented in November and so far it is going very well. Much of the success of this new initiative is due to you (following the new process)! We are continuing to work to expand the functionality of CertView to better help you use your certification as a tool to help improve your career.

Also in this issue of the EMagazine, we are announcing several new offerings. We have a new SQL Tuning certification as well as a new Exam Preparation Seminar. We have continued to release new Exam Preparation Seminars and Exam Preparation Seminar Value Packages and we are receiving good feedback. We hope that you will consider employing one of these seminars to help you prepare for your next certification exam. They are now even available on iPad!

Thank you and good luck!

New Process For Receiving Oracle Certification Exam Results
On November 15, 2012, Oracle Certification exam results became available directly from Oracle's certification portal,CertView. After completing an exam at a testing center, you will login to CertView to access and print your exam scores by selecting the See My New Exam Results Now link from the homepage.

AUTHENTICATE YOUR CERTVIEW ACCOUNT NOW
One very important step you must take is to authenticate your CertView account BEFORE taking your exam. This way, if there are any issues with authorization, you have time to get these sorted out before testing. Keep in mind that it can take up to 3 business days for a CertView account to be manually authenticated, so completing this process before testing is key! You will need to create a web account at PearsonVUE prior to registering for your exam and you will need to create an Oracle Web Account prior to authenticating your CertView account. The CertView account will be available for authentication within 30 minutes of creating a Pearson VUE web account at certview.oracle.com.

GETTING YOUR EXAM RESULTS FROM ORACLE
  • Before taking the scheduled exam, you should authenticate your account at certview.oracle.com using the email address and Oracle Testing ID in your Pearson VUE profile. You will be required to have an Oracle Web Account to authenticate your CertView account.
  • After taking the exam, you will receive an email from Oracle indicating that your exam results are available atcertview.oracle.com
    • If you have previously authenticated your CertView account, you will simply click on the link in the email, which will take you to CertView, login and select See My New Exam Results Now.
    • If you have not authenticated your CertView account before receiving this notification email, you will be required to authenticate your CertView account before accessing your exam results. Authentication requires an Oracle Web Account user name and password and the following information from your Pearson VUE profile: email address and Oracle Testing ID.
      • Click on the link in the email to authenticate your CertView account
      • You will be given the option to create an Oracle Web Account if you do no already have one.
  • Tips
    • Please allow one hour after you create your Pearson VUE web account, before you attempt to authenticate your CertView account, to allow enough time for the data refresh in Oracle's database.
    • If you already have an Oracle web account, do not create a new one. If you already have an Oracle Web Account but need help retrieving your user name/password click here
    • If there is a technical issue that affects the function of the 'See My New Exam Results Now' link, you can access your exam results by signing in to CertView, and clicking on the Certification Status and then on Exam History. Results will be available here by 24 hours after you have taken the exam.
After account authentication, you will be able to login to CertView and select See My New Exam Results Now to view your exam results or Print My New Exam Results Now to print your exam results.

As always, if you need assistance with your CertView account, please contact Oracle Certification Support.

"Meet The Author": Harry Foxwell

Join Harry Foxwell - author of "Oracle Solaris 11 System Administration: The Complete Reference" - as he discusses the book in this video, including detail about why the book was written, details about the target audience, and what he's excited about in Oracle Solaris 11.


The Real Value Of Certification
By Brandye Barrington on Nov 05, 2012

I read a quote recently by Rich Hein of CIO.com "Certifications are, like most things in life: The more you put into them, the more you will get out." This is what we tell candidates all the time. The real value in obtaining a certification is the time spent preparing for the exam. All the hours spent reading books, practicing in hands-on environments, asking questions and searching for answers is valuable. It's valuable preparation for the exam, but it's also valuable preparation for your future job role and for your career. If your goal is just to pass an exam, you've missed a very important part of the value of certification.
The Real Value Of Certification
We receive so many questions through different forms of social media on whether or not certification will help candidates get jobs or get better jobs. Surveys conducted by us and by independent entities all point to the job and salary benefits of certification. However, a key part of that equation is whether a candidate can actually perform successfully in a job role. If preparation time was used to practice and learn and master new skills rather than to memorize a brain dump, the candidate will probably perform successfully in their job role, and job opportunities and higher salary will likely follow. Candidates who do not show that initiative, will not likely reap the full benefits of certification.

Keep this in mind as you approach your next certification exam. You are preparing for a career, not an exam. This may help you to be more appreciative of the long hours spent studying!
