Facing VMware Interview

– How to face Any interview ?
– VMware technical questions to be prepared by Freshers and Experienced people

 

Please keep in mind, don’t just go and face the interview after going through this post. I am writing this blog post just for your reference, so don’t blame me if you are not selected 😉

What I think is, no matters which interview you are going to face, you have to be confident answering all technical and non-technical questions. We are technical people so always use your LOGIC 🙂  I am very sure that you can answer the technical questions very well, but you will be nervous in answering some tricky non-technical questions. The interviewer is also a human being and he/she has faced or going to face the interview in near future, nobody is parmanent in this crual IT industry, so make him/her feel comfortable or they just gets annoyed because of foolish answers. The best way to prepare for any interview is, WRITE DOWN the questions you think will be hard to answer. Ask yourself, trust me, you know what you are capable of, you know what you can face, so why don’t you just prepare?

 

Logical Interview Questions:

  • How would you describe yourself? Or Tell us something about you Or Describe yourself
  • Why are you leaving your last company?
  • How do you handle pressure?
  • How long do you expect to work for this company?
  • why do you want to work here?
  • What are your goals for the future?
  • What are your weakness?
  • Why should we hire you?
  • Can you work in shifts?

Can find some more on google 🙂

 

Mostly Freshers are facing difficulty in answering these questions. So I strongly recommend, to WRITE DOWN such questions and the best answer in your OWN LANGUAGE. Be honest, they won’t punish you. I can’t write the answers of above questions as this is a technical blog and I have to cover almost 100 technical questions.

 

Honestly, I am also prepering for Technical VMware questions and I think the best way is to write a blog post to prepare 🙂

    Really good article.

    My answers for logical questions would be…

    Why are you leaving your last company? For Better Prospect, more exposure on diff environment/platforms.
    How do you handle pressure? I will prioritize work as per severity of work.
    How long do you expect to work for this company? till I will reach my goal. :-p
    why do you want to work here? I always wanted to work with BRAND like your company.
    What are your goals for the future? I wish to reach Himalayan heights in IT industry.
    What are your weakness? I am strong enough to do this job. 🙂
    Why should we hire you? I would be an asset to your company, not a liability.
    Can you work in shifts? YES. 🙂
