Something like this should work. It should just be a matter of using the correct string manipulation functions: https://docs.cloudera.com/documentation/enterprise/6/6.3/topics/impala_string_functions.html

create table test1 (col1 string);

insert into table test1 values ("IT Strategy& Architecture BDC India [MITX 999]"), ("Corporate & IC Solution
Delivery [SVII]"), ("Operations Solution Delivery [SVIA]"), ("Mainframe Service [MLEM]"), ("Strategy & Architecture [MLEL]");

select * from test1;
+------------------------------------------------+
| col1                                           |
+------------------------------------------------+
| IT Strategy& Architecture BDC India [MITX 999] |
| Corporate & IC Solution Delivery [SVII]        |
| Operations Solution Delivery [SVIA]            |
| Mainframe Service [MLEM]                       |
| Strategy & Architecture [MLEL]                 |
+------------------------------------------------+

create table test2 as select trim(split_part(col1, ' [', 1)), trim(concat(' [', split_part(col1, ' [', 2))) fr
om test1;

select * from test2;
+-------------------------------------+------------+
| _c0                                 | _c1        |
+-------------------------------------+------------+
| IT Strategy& Architecture BDC India | [MITX 999] |
| Corporate & IC Solution Delivery    | [SVII]     |
| Operations Solution Delivery        | [SVIA]     |
| Mainframe Service                   | [MLEM]     |
| Strategy & Architecture             | [MLEL]     |
+-------------------------------------+------------+
