My friends often seek my advice on quiting job and negotiating salary. I have helped many! I have quit my job way too many times and my last change was with a 95% hike! So here’s how I go about it.When it comes to salary, most of the times, it’s that one HR recruiter who decides your pay. You have to rip her (almost always, her) confidence apart right in the interview room.How you project yourself :- Wear decent cloths, not superfluous. Business casual is perfect. I don’t wear full sleeves for interviews. Learn to project yourself as I-mean-business guy than I-need-a-job junkie. You said you have good language skills, use every sentence to impress your HR recruiter. Business idioms are best to grab her attention. Use your body language as well. If you are sitting across the table, lean forward, keep both your elbows on the table. Be mindful of your body language. Do these help you get a better salary? No, it’s just for an impression.Skills - most important thing :- If you are unskilled, nothing would save you, Period! You mentioned that you know some advanced technology. Fair enough! Do you have something to show off on your github? Have you created something of your own? Do you have a contribution to some popular tools? Do you have a technology blog? Have you won some tech challenges? Have you highlighted all this, whatever applicable, on the front page of your resume?Remember, only you will see your potential, ie, what you are capable of doing, everyone else judge you by what you’ve already done! Sad truth. So get some shit done! No excuses here.Don’t ask for a job, go sell yourself :- This might sound clichéd, but very important. The difference is, when you walk into the interview room, do you feel you desperately need that job? Failure! You should think why this company should be desperate to hire you. It must be so. To make this point clear - every HR interview begins with a bit of suffocation. And the plot is that the company is selling a job, you are there to buy it. You’ve gotta flip that! You’re selling something hot and the company would benefit from it. Funda of sales! So turn it around!But in the beginning, she is psychologically at a higher level and you’re at bottom - that’s how it’s staged. Rip off your HR interviewer’s confidence. There are many ways. For example, she would probably talk about the work-life balance at her company and how you could benefit from that! You might want to say ‘wonderful!‡ Don’t! Listen intently, patiently until she stops, then ask her - ‘Every other company has this to offer, tell me something that makes you outstanding? I’m curious!‡ Say that with wide-open eyes. Your goal is to bring her down! Be cautious to be polite! Research her company's competitors, and find out what, where they lack. Use them against her to put her under pressure. Listen so intently that you should find something to use against her. This will work in your favor.Speak, speak, speak :- HR recruiters follow 80–20 rule. She speaks 20%, you 80%! Use it wisely. Inflate your profile. First bring her down to your level (psychological), then go above her! Ask all sort of questions. You want to know everything about your prospectus employer! Watch her struggle to answer your genuine questions that you would like to know of her company and the opportunities once you join them. You should invoke a guilt in her that this qualified chap has other better options, better companies than the one she represents. The more you put her under pressure, the more you get out of the interview.After this, when she takes the conversation to your salary expectation, be bold and ask, like you’re worth it. Be clear about your expectations. If you're not bold, it’s easy for her to negotiate. You should ask the maximum her company can give the best candidate for the job you’re applying. If she refuses and asks if that’s negotiable, tell her you may consider that. This is only for not getting rejected right away, just in case what you asked for is impossible. But don’t ever settle for less. Your goal here is to get the offer, whatsoever.Negotiation :- If you get an offer letter with less than what you expected, reject it. Don’t give reasons. If you get what you asked for, reject anyway. Your goal here is, get her coming back to you. Tell her, while you were waiting for her offer, you got a better one. But you would still like to join her company (for all that work-life balance and shit), if she could reconsider your package! If she asks you to disclose the new offer, just remind her that all offer letters are confidential. Tell her that you’re still interested in her offer. Now you have turned the game upside down. You are selling yourself, she’s the buyer! Well done!Go shopping :- Once you have an offer, go shopping with it! You’re on the safer side. Ask for more, just walk in the interview room and demand. Be ready to walk away, too. Tell them, buy me for what I sell you for, I’m on my way to glory!I declined my Accenture job offer with one word in the reply email - ‘Rejected.‡ I got a call from HR in 10 minutes. Now, at this moment, she was asking me to reconsider, and I was to decide. This is how you flip it.However, I had my toughest negotiation with Accenture HR. We were struggling to conclude and I hang up the phone saying ‘You decide the best you can and let me know, you will have my final answer in 10 minutes.‡ I assumed I was out of the game, but I got an amended offer letter. We compromised - both of us, and I accepted that offer. After few days of my joining, using ‘thank a colleague‡ portal, I sent her a ‘thanks‡ to let her know she was impossible!Disclaimer :- Be extremely cautious to be polite and soft-spoken! You by no means offend the HR recruiter. Be curious with every question you ask. Also, this may not always work. If you’re applying a job at amazon and the likes, don’t play this! Be responsible for what you get in return. Reject some offer anyway! Feel awesome that way (like a boss)! She may ask you to leave the room, expect that as well! But try again! If you don’t risk it, you ain’t gonna win it.
