Ho presentato la mia candidatura tramite un selezionatore. La procedura ha richiesto 2 settimane. Ho sostenuto un colloquio presso Box (Los Altos, CA) nel mese di ago 2012
Colloquio
I did a set of interviews at Box very recently.
My first impression of the place is that it's a nasty commute to get to, if one doesn't live close by on the Peninsula. Traffic to get to & from the office on El Camino Real seems very likely to be a snarl during the day, and if you're doing Caltrain, be certain to catch the right train, or else you might not make the shuttle you were hoping for.
I did see the giant slide in the lobby from the 2nd floor. According to the front desk receptionists, it's rarely used. Before going into your interview, you can pick up a few cold drinks (sodas, water, etc.) from the cooler that's right in the lobby.
The work environment is of the large room with worktables variety (i.e. no cubicles, minimal personal space and nowhere to hide where one can just concentrate on what's in front of you). Various meeting rooms and server closets (presumably) break up the workspace areas a bit.
Interviews are conducted in those meeting rooms. They have the glass walled "fishbowl" kind of meeting rooms (where everyone walking or rolling by on scooters can peek in and see you doing your whiteboard dance) and others that are four solid white walls (where you write your whiteboard answers on the walls… the scrawling from the markers doesn't clean off the walls super well but they can be erased with some effort).
They had a few people from my potential team talking with me and then a couple others from a non-related team. One of the interviews was a team, where one of the interviewers had a silent partner sent along to observe (and learn) how Box ritually slaughters their candidates.
I got to step into the recruiters area and they have a white board full of names where offers have been extended, indicating they are hiring aggressively (which also can be seen as a potential danger sign… binging on a large amount of new hires can lead to purging when today's dot com 2.0 boom times turn bad).
Don't assume getting in here for an on-site interview means a job at Box is a shoo-in though: even though Box is apparently in dire need of help with my expertise (and the team I interviewed with is supposedly short staffed for the amount of work they have on the books to do), I clearly fouled up at least one of my interview answers and that's most certainly what got me vetoed from getting an offer. Study up on specifics closer to whatever type of developer role your interviewing for, but also be ready for general computer science topics (ala traditional Apple or Google interviews). Good luck!
Domande di colloquio [3]
Domanda 1
Identify where potential race conditions can happen in this hardware & database configuration:
1) validate that folder Z already exists in cache or in the db
2) invalidate cache data for Z
3) INSERT file 'c' into folder Z
4) gather folder Z + children
5) update cache with new information about folder Z
hardware set-up would be as follows:
--- cache machine 1
// --------------------------- \\
outside world -- --- cache machine 2 --- database
\\ --------------------------- //
--- cache machine 3
While any machine might be asked about files within folder Z, the actual data of folder Z will be cached on exactly 1 machine out of any of the machines that have cache data.
If you speak with a dramatically senior engineer (i.e. old-school Comp Sci, not to mention much more senior than anyone else you'll ever see at Box,) this is the question he's likely to shoot at you:
Given an integer of a certain bit length, does it have an even or odd number of parity bits?
Ho sostenuto un colloquio presso Box (Varsavia, Masovia)
Colloquio
First interview was algorithms in my case using priority queue (in this part I was allowed to use internet).
Next part was divided into 4 interviews: behavioral, with hiring manager, design (design elevator system) and live coding algorithm.
It's nice that they provide feedback from the interview.
In the end I didn't get an offer because according to them I lacked experience, even though according to feedback all my interviews went well. I feel they wasted my time because I didnt apply for this position, they contacted me on linked in.
Ho presentato la mia candidatura online. Ho sostenuto un colloquio presso Box (Redwood City, CA)
Colloquio
5 rounds of algorithms and data structures, retrospective and behavioral questions to assess culture fit. I did well on the retrospective but did not do good in other rounds. It is a fairly detailed process.
very long and tedious, too many stages and communication was good but not always clear, i wish it was more streamlined and clear. Not the best or the worse i must say,.
