Software Engineer IV was asked...April 12, 2012

Two people are each stuck on their own island, connected by a ferryman with a lockable box. Each person has their own lock and key, but can't send the key along with the box. One person wants to send the other a diamond, but it must be placed into the box and locked or it will be stolen by the ferryman. How do you send the diamond without the ferryman stealing it?

10 Answers

1) person A sends key only in a unlocked box to person B. 2) person B sends key only in a unlocked box to person A. 3) 3rd trip person A puts diamonds in the box snaps the lock their holding closed. (At this point owner of the lock can't open the lock. Ensure all contents are in the box before engaging lock.) 4) once the lock box arrives to person B, they can use the key provided on the trip before to open and stare at the contents, And realizes he can pay the ferryman to give him/her ride off the island. Then place a thank you note in the box and close with lock initially held by person B and which now person A has the key. Option B for #4 step) send a thank you note and lock with which the diamonds were so cleverly send to you sealed with. ;) *** Now follow up question would be, how to ensure the ferryman didn't copy the keys during the first transfer of keys? Answer) well, I guess you could have exchanged open locks and not the keys between the two people, and if he could copy a lock on a boat - the ferryman should be looking into more rewarding currier. But why do they care about diamonds when their stuck on an island, not stranded just stuck - pay the ferryman. There is always a man in the middle, know what to trust and what not to. Focusing on security when you may have bigger problems is useless. Less

Step 1: The person with the diamond, puts it in the box, locks it with his lock (Let's say Lock1). The ferryman takes it across. Step 2: Person 2 locks the box again with his lock (Lock2) Sends it back with the ferryman. Step 3 : Person 1 unlocks Lock1. Sends it back. Step 4 : Person 2 unlocks Lock 2 and retrieves the diamond.

The upvoted answer has a flaw. The rules state you cannot send your key in the box. Here's how I'd solve it. 1) Person A sends a note in the box unlocked saying send me your lock open. If writing materials are not available, they can send a verbal message with the ferryman. 2) Person B places their lock inside the unlocked box and sends it back 3) Person A places the diamond in the box and locks it with Person B's lock 4) Person B receives the locked box, opens it with their key.

Generally correct; but not perfect.

There's a lot of elements to typically cover in these questions, clarifications, scoping, making sure you're answering the actual question the interviewer is looking for you to answer, etc. Could be worth doing a mock interview with one of the Prepfully Cisco Software Engineer IV experts... they've worked in the role so they clearly know how to get through the interview.

Do you see want to be in management?

1 Answers

I'm happy doing engineering work and know that I'd probably be equally happy in management. I wasn't quite sure, however, why they asked the question. I was tempted to respond, "Of course I want to be a manager. Easier work, more money. Count me in." But if they were looking for someone who wanted to stay technical and I said I wanted to grow into management, they might have told me "Thanks, but no thanks" because I didn't fit their bill. I opted to tell them that I was, in fact, interested in management. Less

There's quite an extended back and forth in actual interviews for questions like this, so nothing quite like real practice. The Prepfully Cisco Software Engineer IV experts have actually worked in this role, so they're able to do an honest-to-God accurate mock, which really puts you through the paces. Less

The key in these questions is to cover the fundamentals. There's usually a back-and-forth with the interviewer. Might be worth doing a mock interview with one of the Cisco Software Engineer IV experts on Prepfully? They give some real-world practice and guidance, which is pretty helpful. Less

What's it going to take to get you to accept this job?

Technically speaking, this is a negotiation question but, I think, is a very difficult one for most people to answer. It always is for me. When this question is posed, your answer can lead directly to 1) a change in employers, 2) a withdrawn offer or 3) you dining on a plate of crow. In 1), you're naming your price, essentially saying you'll take the job if they have no problem with the price you name. The question as posed essentially has everyone put their cards on the table and ends the negotiation process. In 2), you might just price yourself out of the job and paint yourself as greedy, difficult and/or unrealistic, resulting in a withdrawn offer. It can , however, be the "professional" way of saying no to a job you're too nervous to take, providing you don't put the price too high. Say, for instance, that you want four weeks of vacation a year and they won't budge beyond three. That's understandable and realistic. If you say you want six months, that's greedy, difficult and unrealistic. In 3), you might offer a price for yourself that the employer is unwilling to pay. Let's say you really want or need the job, but you're trying to get as much as you can, so you name your price. Let's say that the employer doesn't like your price and then says, "Sorry. That's too much. We regretfully withdraw our offer. Have a nice day." In that case, since you desperately want/need the job, you might have to eat crow and back off on your price, indicating to the employer that that wasn't your price at all, that maybe your jerking their chain, that you really want the job and that they can offer whatever they want to you. Know what you're doing and what you really want when this question comes up, because it always does when the number of offers is greater than one. Less
